“Where’s the cheapest place to buy LEGO?” doesn’t have a single answer — it depends on whether you want a specific brand-new set, are happy with pre-owned, or just want the most bricks for your money. Here’s how the options really stack up, from everyday retail to the place most value-hunters end up.
Retail sales and clearance
Big-box stores (Walmart, Target, Amazon) sell current sets at or near RRP, so the savings come from timing, not the store:
- Seasonal sales (Black Friday, back-to-school, holiday toy events) routinely knock 20–30% off popular sets.
- Clearance is retail’s best-kept bargain — sets nearing retirement get marked down hard to clear shelf space. If you can wait, this is where new-in-box deals live.
We compared the two biggest retailers in detail in are LEGO sets cheaper at Walmart or Target? — the short version is “check both the same week.”
Warehouse clubs and online marketplaces
Costco and Sam’s Club occasionally carry exclusive multi-set bundles that beat per-set retail. Online, third-party marketplace sellers sometimes undercut RRP on in-demand sets, though you trade the in-store guarantee for shipping and seller variance.
LEGO’s own rewards
If you buy new directly, the LEGO Insiders program adds points, occasional gift-with-purchase promos, and double-points events. It won’t beat clearance, but for must-have new sets it softens the price.
The real answer for value: the second-hand market
Here’s the thing every “cheapest LEGO” guide eventually admits: for most buyers, pre-owned is the cheapest path, and it’s the only place that wins on retired sets (which only get more expensive at retail-adjacent resellers once they’re gone).

- Used complete sets sell for a fraction of a new box, and kids rarely care that it was opened once. Browse complete sets & packs to see the spread.
- Bulk and by-the-pound lots are unbeatable on cost-per-brick if you just want to build. That’s the domain of bricks, pieces & parts.
- Single minifigures let you chase one character cheaply instead of buying a whole set — see minifigures.
- A little storage & display keeps a growing second-hand collection sorted.
The catch is doing your homework: confirm completeness, check the seller’s feedback, and compare a few listings. But for sheer value-per-dollar, nothing on the new-retail side competes.
So, what’s actually cheapest?
- Cheapest brand-new specific set: wait for a seasonal sale or clearance; check Walmart, Target, and Amazon the same week.
- Cheapest overall / best value: the second-hand market — especially for retired sets, bulk parts, and single minifigures.
- Cheapest per brick: used bulk lots, hands down.
