How we compare prices
A good deal is about more than the price on the box. Here’s how we help you compare LEGO and other building sets, and what to check before you buy.
Start with the set you want
Search by brand and set number to find the right set, then compare the stores listed on its page. We track a range of retailers and brand stores, but we don’t cover every shop. The lowest price we show may not be the lowest price anywhere. Used sets and marketplace search links are shown separately from new retail offers.
How we pick the highlighted offer
We highlight a new set that was in stock when we last checked and has a current price. We compare the price you can pay now, including shipping where we can estimate it. If shipping is unknown, the item price is only a starting point: the total may be higher at checkout. It’s worth looking through the other offers too. We never treat unknown shipping as free.
Check the time next to the price
Prices and stock can change after we check them. To be highlighted, an offer must have been checked within the last 72 hours, and some offers expire sooner. Old prices, out-of-stock sets and marketplace search links don’t qualify. Always confirm the price and availability at the store before you buy.
Look at what you’ll pay at checkout
Our set comparisons use US prices in US dollars. Where possible, we estimate the cost of buying one set, including shipping and known buyer fees. Your delivery address, tax, minimum order requirements and other checkout charges can change the total. The store’s checkout shows the final amount you’ll pay.
Make sure the deal works for you
Some shipping estimates assume you have a store membership. Look for the membership note beside the offer, and turn off memberships you don’t have in your shipping preferences. A current Prime price or verified coupon can help an offer become our highlighted choice. We show the conditions beside the offer so you can check whether you qualify. Cashback, loyalty points and gift-card benefits are shown separately because they don’t reduce what you pay for the set at checkout.
Use price history as a guide
Price history helps you see how a price has changed since we started tracking it. There may be gaps, and “lowest recorded” means the lowest price in our records—not the lowest price the set has ever sold for. A recommended retail price (MSRP) or a crossed-out reference price can help put a discount in context, but it doesn’t prove anyone previously paid that amount.
How buying through our links supports us
We may earn a commission when you follow an eligible link and make a qualifying purchase. As an Amazon Associate I earn from qualifying purchases. Commission doesn’t decide which offer we highlight; we choose by price and estimated total among offers that qualify. You buy directly from the store, which handles payment, delivery and returns.
