LEGO Sourcing Route: Build One That Pays for Itself

A LEGO sourcing route is a repeatable circuit of thrift stores, garage sales, estate sales, and Facebook Marketplace stops that you hit on a set schedule, so finding inventory stops being random and starts being a system you can run every week. Instead of driving around hoping to get lucky, you're working a route that already knows where the LEGO tends to show up and when.

I've built my own version of this over the years, and the biggest shift wasn't finding some secret goldmine location. It was treating sourcing like a repeatable job instead of a scavenger hunt. When I started tracking which stops actually produced sellable inventory, I cut my dead-end trips by a lot and started spending my gas money where it counted.

• Key takeaway: A route beats random trips because it turns sourcing into a schedule, not a gamble.
• Key takeaway: Thrift stores, garage sales, estate sales, and Facebook Marketplace each have different rhythms, so your route should hit each one at the right time, not just any time.
• Key takeaway: Budgeting per stop and per lot keeps a sourcing trip from quietly eating your margin.
• Key takeaway: Tracking results after each trip is what turns a one-off haul into a route that pays for itself month after month.

What Is a LEGO Sourcing Route?

A LEGO sourcing route is a planned sequence of physical and local-digital stops, thrift stores, estate sales, garage sales, and Facebook Marketplace, that you visit on a repeating schedule to find LEGO inventory to resell. It's the difference between "I'll drive around this weekend and see what's out there" and "Tuesday is thrift day, Saturday morning is garage sales."

In my experience, the word "route" is doing real work here. A route implies order, a schedule you can repeat, and stops you already know something about. Random sourcing trips can still turn up good lots, but a route is what makes sourcing a business function instead of a hobby you do when you feel like it.

Why a Route Beats Random Trips

A route beats random trips because it lets you build knowledge about specific locations over time, restock patterns, staff pricing habits, and typical lot quality, instead of starting from zero every time you go looking for LEGO. That accumulated knowledge is what actually compounds.

I noticed this pattern early on: the thrift stores near me that put out toys on Wednesday mornings were picked clean by Wednesday afternoon if I didn't show up. The ones that restocked on weekends behaved completely differently. Once I mapped that out, I stopped wasting Saturday mornings at the Wednesday stores and started hitting them on the right day. A seller I know runs a similar system across five thrift locations and treats it almost like a delivery route, same stops, same order, same day each week.

Step 1: Map Your Local Stops

Start by listing every thrift store, consignment shop, and regular estate sale company within a 30 to 45 minute radius, then sort them by how often you've found LEGO there in the past. This turns a vague sense of "there are some thrift stores around here" into an actual list you can plan a route from.

Include Facebook Marketplace as a stop even though it's digital, because it behaves like a location with its own restock rhythm. I check it the same way I'd check a physical shelf, on a schedule, not just whenever I happen to think of it. If you're just starting out, brick'em's LEGO minifigure database is worth bookmarking too, since it helps you confirm what you're actually looking at before you decide a stop was worth the drive.

Step 2: Time Your Route Around Restock Days

Timing your route around restock days means calling ahead or watching patterns to learn when each stop puts out new toy donations, then building your weekly loop around those windows instead of a fixed day that ignores them. This single change is usually the biggest lever in how much inventory a route produces.

Most thrift stores restock toys on specific days tied to donation processing, often early in the week after weekend drop-offs pile up. Garage sales cluster on Friday and Saturday mornings, with the best lots usually gone within the first hour. Estate sales frequently run multi-day, with day one priced higher and later days offering markdowns, so I'll sometimes hit the same estate sale twice, once early for the good stuff, once late for a deal on whatever's left. Estate sales are also where I've found the oldest inventory. LEGO's stud-and-tube brick design has stayed compatible since 1958, so a bin of decades-old bricks at an estate sale can still click together with sets sold today, which is part of why vintage lots draw collector attention.

How Much Should You Budget for a Sourcing Trip?

A sourcing trip budget should cover gas, a per-stop spending cap, and a separate "big lot" reserve you only tap when you find something clearly underpriced, and most resellers do better setting that budget before they leave the house rather than deciding in the moment. Buying without a number in mind is how a good trip turns into a break-even one.

I personally set a soft cap per stop and a hard cap for the whole trip. If I blow through the soft cap on one incredible bulk lot, I recommend adjusting the rest of the route rather than pretending the budget didn't exist. Before committing to any lot that's bigger than an impulse buy, I run it through brick'em's haul calculator so I'm pricing the lot against real numbers instead of a gut feeling in a parking lot.

Sourcing Route Checklist

A pre-trip checklist keeps a sourcing route consistent even on days you're rushed, and consistency is what separates a route that pays for itself from one that just burns a Saturday. Here's the checklist I actually use before heading out.

• Cash and a card, since some estate sales and garage sales are cash-only
• A phone with your pricing app or brick'em open and charged
• A rough per-stop and per-trip spending cap written down, not just in your head
• Bags or bins for sorted vs. unsorted finds
• A short list of your top 3 to 5 stops in order, with backup stops if one's a dud
• A notes app entry to log what each stop had, even if you didn't buy

Stop type	Best timing	What to look for
Thrift stores	Morning after restock day	Loose minifigure bins, bagged bulk, complete boxed sets
Garage sales	First hour, Friday or Saturday	Kids' toy bins, "everything must go" boxes
Estate sales	Day one for quality, later days for price	Vintage sets, sealed boxes, large personal collections
Facebook Marketplace	Check daily, morning and evening	Local bulk lots, "kids outgrew it" posts

What Should You Actually Buy on the Route?

Buy what you can identify and price with reasonable confidence, and be cautious about large unsorted lots unless the asking price already assumes a lot of the contents are junk. The goal on the route itself isn't to fully evaluate every piece, it's to make a fast go or no-go call and finish the deeper pricing later at home.

In my experience, minifigures are the single best thing to keep an eye out for on a route because they're small, easy to carry, and can carry surprising value relative to their size. I've seen figures worth $200 to $300 sitting in a dollar bin because nobody at the store knew what they were looking at. Instruction manuals are another overlooked category. Most common ones only bring $2 to $5, but rare manuals have sold for as much as $300, so I don't toss loose manuals into the giveaway pile without a second look anymore. When I sort through a haul afterward, I run anything questionable through brick'em's scanner and cross-check it against the minifigure database before I commit real time to cleaning and listing it.

Turning Finds Into Cash: The Route Doesn't Stop at the Trunk

A sourcing route only pays for itself once the inventory actually sells, so the route should end with a plan for where each type of find goes, not a growing pile in your garage. Sorting as you unload the car saves hours later.

I generally split finds three ways: minifigures and small valuable parts go toward BrickLink and Whatnot, mid-tier lots and sets go toward eBay where broader demand helps them move, and anything I'm not sure about goes into a "price later" bin I revisit weekly. I've personally sold over $100,000 worth of LEGO on eBay over the years, and almost all of that inventory started as a routine sourcing stop, not some rare find. One caveat worth planning for: eBay promoted listings can push your effective take rate close to 25% on items that need the extra visibility, so I factor that into what I'm willing to pay for a lot before it ever leaves the store. Facebook Marketplace lots I bought locally sometimes go right back onto Facebook Marketplace if they're already priced right and I just want to flip fast. Before I commit shelf space to a big haul, I like running the full lot through brick'em's collection value calculator so I know roughly what I'm sitting on.

How Often Should You Run Your Route?

Most active resellers run a core sourcing route once or twice a week, with lighter Facebook Marketplace checks daily, since toy donations and local listings replenish faster than most people expect. Running it too rarely means missing time-sensitive garage sales and fast-moving Marketplace posts.

I started with one big Saturday loop and added a shorter Tuesday thrift-only loop once I noticed how much got restocked mid-week. That's a personal rhythm, not a rule, and your version should match your local restock patterns and how much time you actually have. The point of a route is that you can scale it up or down without having to reinvent your plan every single week. If you want more route and sourcing breakdowns like this one, brick'em's blog has other reseller guides worth working through.

Frequently Asked Questions

How much LEGO inventory do I need to start a sourcing route?

You don't need existing inventory to start, you need a plan. Begin with two or three reliable stops and one Facebook Marketplace check per day, then expand your route as you learn which locations actually produce sellable lots for you.

Is it better to source LEGO alone or with a partner?

Either works, and it comes down to coverage and trust. A route partner can cover twice the stops in the same morning, but I recommend agreeing on spending caps and how lots get split before you're standing in a store deciding together.

Should I buy a LEGO lot if I can't identify most of the pieces?

Only if the price already assumes that. Unsorted bulk priced like scrap plastic can still be worth it, but paying a premium for a lot you can't evaluate is one of the fastest ways to turn a sourcing trip into a loss.

How do I know if my sourcing route is actually profitable?

Track what you spend per trip against what that trip's inventory eventually sells for, not just what looks good in the moment. A route that feels productive but never gets measured is hard to improve.

Do thrift stores negotiate on LEGO prices?

Some do, especially for bulk unsorted bins, but most chain thrift stores have fixed pricing. Independent and church-run thrift shops tend to have more flexibility, so it's worth asking, especially on large lots that have been sitting a while.
