There isn't one "best" place to sell used LEGO — there's a best place for what you specifically have and how much effort you want to put in. Here's how the main options actually compare.
eBay — Best for Individual Sets and Speed
eBay's massive buyer base means things sell fast, and it's a solid fit for complete sets or notable individual pieces you want in front of the widest possible audience. The tradeoff is fees — eBay's total selling costs (final value fee plus any promoted listing spend) commonly run well into double digits as a percentage of the sale, higher than many other marketplaces.
BrickLink — Best for Parts and Serious Collectors
BrickLink is the largest dedicated LEGO parts marketplace, with by far the deepest catalog for tracking down specific pieces. It's the natural home for individually listing loose parts at real market value — but it comes with real setup, knowledge, and ongoing effort: cataloging what you have, pricing each item, and packing individual orders as they sell.
Facebook Marketplace — Best for Local, No-Shipping Sales
Selling locally means no shipping costs or packaging hassle, and it's often the fastest way to move a large mixed lot to someone who wants it as-is. The downside is a smaller buyer pool and more back-and-forth negotiating, since local buyers often expect to haggle.
Bulk Buyback programs — Best for Zero Sorting
Services that buy loose LEGO by weight (Sell Bricks Online, Lego Replay) trade some per-piece value for total simplicity: no listing, no photographing, no waiting for the right buyer. You box it up once, ship it, and get paid. It's the right call when what you have is mostly common, mixed pieces and your priority is getting it out of the house with minimal effort.
Quick Comparison
- Want it gone fastest with the least effort? Bulk buyback program.
