Amazon Prime Deals: 88 LEGO Sets at Their Lowest Ever Amazon Price

It's Amazon Prime deals week, and I've been through the list of what's on offer to find the best options for investors and early Christmas shoppers. These 88 LEGO sets are all at the lowest price we've seen in the last six months across every retailer we track - and with more than 250,000 retailer prices in our database, you can bet these are the best you will find.

You will need a Prime subscription for these to be worthwhile, but if you're picking up a few sets it might be worth the cost of entry. Sign up for Amazon Prime here.

We've split the list up to make it easier to shop: sets that are retiring soon first, then the big-ticket discounts, Christmas gift ideas, display pieces for adult builders and stocking fillers under £25.

Retiring Soon: Last Chance at These Prices

23 of the sets at record-low Amazon prices are due to retire within the next year, or have already been retired by LEGO. Once Amazon's stock goes, these don't come back - so if any of them are on your list, this is the section to act on first.

Hogwarts™ Castle: The Main Tower (76454) - £142.99 (RRP £229.99, save £87.00)

The centrepiece of the modular Hogwarts system and the best retiring-set deal in the sale. £142.99 beats Amazon's previous low of £147.24, and it's the cheapest in-stock price we can find anywhere right now - Very is at £160. It's due to retire in July 2027. See the full price history.

Volvo EC500 Hybrid Excavator (42215) - £242.19 (RRP £349.99, save £107.80)

More than £100 off the big Technic excavator, and it retires at the end of December. Amazon's previous best was £249.00, and the next cheapest retailer we track is at £284.99. See the full price history.

NASA Artemis Space Launch System (10341) - £185.99 (RRP £219.99, save £34.00)

The Artemis rocket was at its full £219.99 at Amazon a week ago, and every other retailer we track is still at or near full price. £185.99 edges under Amazon's previous low of £186.98, and with retirement due in December 2026 there may not be many more chances. See the full price history.

Big Boy Discounts

The expensive sets - the ones that rarely see a proper discount and where 15% off means real money. None of these are retiring soon, but all of them are at their lowest ever Amazon price.

Star Trek: U.S.S. Enterprise NCC-1701-D™ (10356) - £296.99 (RRP £349.99, save £53.00)

The Enterprise-D has sat at its full £349.99 for as long as we've been tracking it - Amazon included, right up until this week. £53 off is the first discount we've recorded on it, and the other retailers we track are still charging full price. If you've been waiting for it to move, it just has. See the full price history.

THE LORD OF THE RINGS: RIVENDELL™ (10316) - £355.99 (RRP £429.99, save £74.00)

Rivendell at £355.99 is £74 below RRP and beats Amazon's previous low of £364.99. LEGO itself is still charging the full £429.99. For a 6,000-piece set that's a serious saving. See the full price history.

Neuschwanstein Castle (21063) - £152.99 (RRP £239.99, save £87.00)

£87 off, which is 36% below RRP. Neuschwanstein was £199.99 at Amazon a week ago, and the next cheapest retailer is still at £195.99. See the full price history.

Great for Christmas

Play sets and crowd-pleasers in the £25 to £80 range - the sort of thing that goes under the tree. Buying now rather than in December means you're getting the record-low price rather than hoping it comes back.

The Going Merry Pirate Ship (75639) - £79.99 (RRP £119.99, save £40.00)

The Going Merry is the flagship of the One Piece range, and £79.99 is a third off RRP. Amazon's previous low was £87.99, and it's cheaper than any other retailer we track right now. See the full price history.

Display Pieces for Grown-Ups

Sets designed for a shelf rather than a toy box - cars, animals and a few film and football favourites.

Stocking Fillers Under £25

Small sets at small prices. The Speed Champions cars and the DUPLO Fire Truck are easy wins.

How Long Will These Prices Last?

Prime deal prices are tied to the event and Amazon's pricing changes constantly, so expect these to move once it ends - and some will sell out before then. You will need a Prime subscription to get them: sign up for Amazon Prime here.
