Where to Sell LEGO: A Platform-by-Platform Comparison

Category: Selling

By BrickBucks

Bricklink, eBay, Facebook Marketplace, Mercari, LEGO trade-in — here's which platform wins for which kind of LEGO.

There's no single best place to sell LEGO. The platform that maximizes your return depends on what you're selling, how much time you want to invest, and how patient you are. Here's a head-to-head comparison of every serious option in 2026, with concrete recommendations for which to use when.

Bricklink

Best for: individual parts, complete used sets sold to dedicated collectors, rare minifigures.

• Fees: 3% of sale price (the lowest of any platform).
• Audience: dedicated LEGO collectors and builders. Most knowledgeable buyer base on the internet.
• Learning curve: steep. Setting up a store, building a parts inventory, and managing orders takes real time investment.
• Speed of sale: slow on common items, fast on rare items.
• Realized prices: highest in the market on parts and rare collectibles.

Bricklink is the answer for anyone serious about reselling. If you have a parts inventory worth more than ~$1,000, Bricklink will out-earn any other platform on a per-part basis. See our 9 Bricklink selling tips.

eBay

Best for: sealed retired sets, headline collectibles, fast sales.

• Fees: 13-15% final value fee (varies by category and store tier), plus payment processing.
• Audience: largest of any platform. Reaches both collectors and casual buyers.
• Learning curve: moderate. Listing is easy; pricing and shipping correctly takes practice.
• Speed of sale: fastest for sealed sets. Auctions clear in 7 days; Buy It Now with Best Offer often clears in 1-2 weeks.
• Realized prices: strong on sealed retired sets, weak on individual parts vs Bricklink.

The eBay rule of thumb: anything sealed, retired, and recognizable should go here first.

Facebook Marketplace

Best for: bulk lots, local pickup, large/heavy items that cost too much to ship.

• Fees: $0 for local pickup, ~5% on shipped sales through Facebook checkout.
• Audience: local, hit-or-miss. Lots of casual buyers and parents looking for cheap LEGO for their kids.
• Learning curve: minimal.
• Speed of sale: variable. Cheap bulk lots sell in hours; pricier collectibles can sit for months.
• Realized prices: lower than Bricklink/eBay for individual sets, competitive for bulk by-the-pound lots.
• Risks: lots of "is this still available?" messages, no-shows, and lowball offers.

Mercari

Best for: mid-tier used sets, when you want lower fees than eBay.

• Fees: 10% flat selling fee + 2.9% + $0.50 payment processing.
• Audience: smaller than eBay, growing.
• Learning curve: minimal.
• Speed of sale: moderate. Quicker than Bricklink, slower than eBay for big-ticket items.

OfferUp

Best for: local bulk sales as a Facebook Marketplace alternative.

Similar dynamics to Facebook Marketplace but lower traffic in most markets. Use as a secondary listing channel — list on both, sell on whichever fires first.

Craigslist

Best for: bulk lots in major metros, particularly if you're selling a collection at scale.

Free listings, no fees. Lower traffic than Facebook Marketplace in most cities, but still a valid second-listing channel for large lots that would be expensive to ship.

LEGO's official trade-in program (BrickLink Replay / LEGO Replay)

Best for: donating bulk loose LEGO with no profit motive.

LEGO's official Replay program accepts donated used LEGO, cleans it, and redistributes to children's charities. You get a prepaid shipping label and a tax-deductible receipt. You do not get cash. Worth knowing about for the bulk loose LEGO you don't want to spend time selling.

Bulk lot buyers

Several US-based companies (Pley/Pleygo, Brick Recycler, We Buy Bricks) will buy bulk loose LEGO outright by the pound, typically at $4-$8 per pound. You ship them everything; they cut you a check. The price is below retail-bulk levels but the speed is unbeatable. Worth it for non-enthusiast inheritors of LEGO collections.
