If you're wondering where to buy LEGO sets to part out, the short answer is Facebook Marketplace, eBay bulk lots, yard and estate sales, and retired sets you catch on clearance before they disappear. I've sourced from all four over the years, and each one solves a different problem depending on how much time, cash, and patience you're working with.
Parting out means buying a complete set, or a whole lot of them, and breaking it down into minifigures, individual pieces, instructions, and sometimes the box, then selling each piece separately for more than the set cost as a whole. It's one of the oldest tricks in LEGO reselling, and in my experience it still works because most casual sellers price a set based on what they remember paying for it, not what the parts inside are actually worth today.
Key takeaways:
- Facebook Marketplace and yard sales are usually the cheapest sourcing channels, but they cost you driving time and require haggling.
- eBay bulk lots let you source from your couch, though promoted listing fees can push a seller's total take rate close to 25% of the sale price.
- Retired or discontinued sets, especially in strong themes like Star Wars, Marvel, and Ninjago, tend to part out for more than sets still in stores.
- Not every set is worth the effort. City-themed minifigures, for example, rarely sell for more than $2 each, so I'd skip parting those out.

What Does It Mean to Part Out a LEGO Set?
Parting out a LEGO set means buying it as a whole, then selling the minifigures, rare pieces, instructions, and sometimes the box separately instead of reselling the set intact. Most parted-out sets bring in more money split up than they would as a single listing, because minifigures and rare parts carry collector demand that the base set alone doesn't capture.
I started parting out sets years before brick'em existed, and the math clicked the first time I bought a beat-up Star Wars set for cheap and sold three of the minifigures inside for more than the whole set would have gone for as one listing. The loose bricks and plates went into a bulk lot. Nothing about that set was special on its own, but broken apart, it was worth a lot more.
Where to Buy LEGO Sets to Part Out
The best places to buy LEGO sets to part out are Facebook Marketplace, eBay bulk lots, yard sales and estate sales, and clearance racks on sets that are being discontinued. Each source trades cash for time differently, and most resellers I know end up combining two or three of them instead of leaning on just one.
Facebook Marketplace is a goldmine for sets that people just want out of the house. Sellers list old sets cheap because they don't know, or don't care, what the minifigures inside are actually worth, and haggling is expected on the platform, so there's usually room to negotiate the price down further. eBay is better for volume. You can filter by "lot" listings and scroll through dozens of mixed sets in a sitting, which is how a lot of resellers build up inventory without leaving the house. Yard sales and estate sales are slower but often the cheapest per set, especially early in the morning before other buyers show up.
Is Facebook Marketplace Good for Sourcing Sets to Part Out?
Yes, Facebook Marketplace is one of the best places to source sets to part out, because sellers there are usually motivated to clear space rather than maximize price. It also lets you avoid platform selling fees entirely if you flip the parts locally, though most resellers still list the valuable pieces on BrickLink or eBay for a bigger audience.
In my experience, the sellers on Facebook Marketplace respond well to offers, so don't be afraid to counter a listed price. That said, safety matters here more than on any other channel, since you're meeting strangers in person with cash or LEGO changing hands. I always recommend meeting at a police station parking lot or another well-lit public spot. Incidents are rare, but the LEGO business has been a target for robberies before, and it's not worth the risk to save a drive across town.
Why Do eBay Bulk Lots Work So Well for Parting Out?
eBay bulk lots work well for parting out because sellers who list mixed LEGO lots almost never sort or identify what's inside, which means valuable minifigures and retired sets slip through at bulk pricing. I've sold over $100,000 worth of LEGO on eBay over the years, and bulk lots have been one of the most consistent ways to restock inventory.
The tradeoff is margin. To get enough eyeballs on a listing when you're selling the parted-out pieces, you often need promoted listings, and that can push your total eBay take rate close to 25% of the sale once you add in standard fees. I've found it still works because the sourcing side is so cheap relative to what a well-identified minifigure or rare part sells for once it's split out and listed on its own.
Should You Buy Retired or Discontinued Sets to Part Out?
Retired and discontinued sets are usually worth buying to part out because their minifigures and pieces stop being produced, which pushes collector demand higher over time. Star Wars, Marvel, and Ninjago sets tend to hold up especially well because those themes have broad, ongoing fan bases that keep buying long after a set leaves shelves.
I personally watch clearance racks hard in the months after a set is announced as retiring, because that's when stores mark things down before the collector premium kicks in. BrickEconomy tracks a lot of this appreciation data if you want to see how specific retired sets have moved in value over time. Just don't assume every retired set goes up. A lot of them stay flat, and the ones that climb tend to be tied to a strong theme or a popular exclusive minifigure.
| Source | Typical Discount vs. Market | Best For | Main Tradeoff |
|---|---|---|---|
| Facebook Marketplace | Often 30% to 50% below market on unsorted sellers | Local sourcing, no platform fees | Driving, haggling, in-person safety |
| eBay bulk lots | Varies widely, best deals on unidentified mixed lots | Sourcing volume from home | Shipping cost and promoted listing fees on the resale side |
| Yard and estate sales | Frequently the cheapest per set | Early-morning bargain hunters | Time-intensive, inconsistent supply |
| Retired set clearance | Store markdowns before resale premium builds | Star Wars, Marvel, Ninjago, and other strong themes | Requires timing and shelf-watching |
How Much Should You Pay for a Set You Plan to Part Out?
A common rule of thumb among resellers I know is to aim for paying 30% to 50% below what you expect the parted-out pieces to sell for combined, which leaves room for fees, shipping, and the time it takes to identify and list everything. That buffer matters more than people expect, because parting out takes real hours, not just a few minutes.
Before I buy, I check the value of the minifigures inside using brick'em's LEGO collection value calculator, since it's faster than pricing everything out by hand. If the set doesn't clear my target margin after that check, I pass on it, even if it looks like a good deal at first glance.

Which LEGO Themes Are Worth Parting Out?
Star Wars, Marvel, and Ninjago are generally the strongest themes to part out because they're highly liquid and appeal to broad, recognizable fan bases. Castle and Pirates sets are underrated for this too, since they attract nostalgic collectors who will pay well for the right vintage minifigure, even if those sets move a little slower overall.
In my view, City is one of the weakest themes to target for parting out. City minifigures rarely sell for more than a couple dollars each, so unless you're buying the set for the pieces or bricks specifically, it's usually not worth the time. Before I commit to a lot, I'll run the figures through brick'em's LEGO minifigure database to confirm which characters are actually worth pulling out and listing on their own.
What Mistakes Do New Sellers Make When Buying Sets to Part Out?
The most common mistake new sellers make is buying a set without checking whether the minifigures inside are actually valuable, then discovering after the purchase that the whole lot barely covers what they paid. I've seen a seller I know buy a stack of City sets thinking bulk meant guaranteed profit, only to realize most of those figures top out around $1 or $2 apiece.
- Skipping a value check before buying, and assuming any LEGO is profitable LEGO
- Ignoring set completeness, which matters a lot if you're planning to resell the set instead of just the minifigures
- Underestimating time cost, since sorting, cleaning, and identifying pieces takes real hours
- Overpaying on Facebook Marketplace because they didn't counter the seller's first price
- Forgetting shipping costs when pricing bulk lots bought sight unseen on eBay
How Do You Sell the Parts After You Buy?
Once a set is parted out, most sellers split their sales across a few platforms based on what they're selling. Minifigures tend to do best on eBay or Whatnot, individual parts and instructions do well on BrickLink, and local buyers on Facebook Marketplace can move whatever's left without any shipping hassle.
When I sort a parted-out lot, I use brick'em's haul calculator to see the total expected payout before I decide which platform gets which pieces. BrickLink is basically the Wall Street of LEGO for pricing individual parts, since sellers there price closer to true market value than on general marketplaces. If you want to build the habit of pricing every haul before you list it, brick'em's free tools are a good place to start.
Frequently Asked Questions
Is parting out LEGO sets actually profitable?
Parting out can be profitable when the set contains minifigures or retired pieces worth more individually than the set costs as a whole. In my experience, margins depend heavily on sourcing price, so buying 30% to 50% below expected resale value gives you room for fees, shipping, and the time spent sorting everything.
What's the cheapest place to buy LEGO sets to part out?
Yard sales, estate sales, and Facebook Marketplace tend to offer the cheapest prices, since many sellers there just want the sets gone and don't know what individual pieces are worth. eBay bulk lots can also be cheap per item, though shipping and promoted listing fees eat into that discount later.
Do I need a complete set to part it out?
No, an incomplete set can still be worth parting out if it contains a valuable minifigure or rare piece. Missing pieces from an otherwise valuable set can often be sourced separately on BrickLink, so incomplete inventory shouldn't automatically get tossed or ignored.
Which LEGO theme is best for beginners parting out sets?
Star Wars and Ninjago are good beginner themes because demand is broad, familiar, and consistent across multiple selling platforms. I recommend starting with a theme you already know well, since recognizing valuable minifigures on sight saves a lot of research time when you're sourcing.
