The Complete Guide to Selling LEGO®


Do you want to sell your old LEGO®? Or do you just want a rough idea of the price you could get? Well, you’ve come to the right place! We’ve put together the complete guide to selling LEGO®. That includes a breakdown of all the best places to sell your LEGO® and how to go about it.

Should I sell my LEGO®?

Are you debating whether to sell your LEGO®? Unsure whether anyone would buy them? Or wondering whether it’s even worth the effort? We’ve put together a list of reasons why you should sell your LEGO®.

1. More money

Selling LEGO® is a great way to earn extra money. You could sell your LEGO® by weight or by complete set. Normally, you’ll earn more money by selling complete sets. You’ll still earn money selling by weight though, which is better than binning your LEGO® and getting nothing!

2. Better for the environment

Selling your LEGO® means that it doesn’t end up in landfill. Instead, it goes to another user who can get years of enjoyment out of it! This extends the product lifecycle and stops it from going to waste.

Reselling your old LEGO® also means that new LEGO® doesn’t have to be produced. There are currently 400 billion LEGO® bricks in circulation, with 36,000 new bricks made every minute. That’s a lot of plastic! Selling LEGO® on the second hand market reduces the need for production, saving plastic and cutting down pollution.

3. Declutter your home

Has LEGO® taken over your home? Sell your LEGO® and reclaim your space. That makes more room for new collections or for other toys as your children get older. You can also check out our organisational tips for the LEGO® you have left.

4. It’s easy to do

It’s so easy to sell LEGO® with WeBuyBricks! Just weigh your LEGO®, enter the weight and get an instant cash offer. Once you’ve accepted the offer, package your bricks and send it to us for free. There’s even an option for free home collection. We’ll pay you the next day, once we’ve received your items.

So, you've now decided you want to sell it, but where exactly is the best place to sell your LEGO®? There are lots of options for selling your LEGO®, including brick-buying sites (like WeBuyBricks), online selling sites and car boot sales. We’ll way up the pros and cons of each of the options to sell your old LEGO® in our complete LEGO® selling guide.

You can also sell your old LEGO® on online selling sites like eBay or Facebook Marketplace. This is the best option if you have a rare LEGO® set.


  • More money - you could earn more money selling LEGO® on online selling sites, especially if you have a rare or collectible set.
  • More control - you can choose what price to set your LEGO® at. Do your research and see what other sellers are selling their LEGO® for.


  • Time-consuming - you could wait months to make a sale, unless you have a set that’s in demand. If you need quick cash, online selling sites probably aren’t for you.
  • Low offers - it can be annoying to deal with low offers from buyers. It can also take a lot of time checking and rejecting bids.
  • Hidden fees - there are often hidden fees with online selling sites, who may take a percentage of your sale. You may also have to pay for postage.

Car Boot Sales

There’s always the option to sell LEGO® at a car boot sale. Pay for a pitch, set up your stall and try to make a sale. This can be a good option if you’ve got lots of stuff to sell at once.


  • Sell multiple items - if you’ve got lots of other stuff to sell as well, car boot sales can be a good way to sell it all at once.


  • Less money - car boot sale go-ers love a bargain and are known for making low offers (often pennies!). You may make more money selling online.
  • Site fees - you have to pay a fee to get a stall. Sometimes, you might not make this money back.
  • Time-consuming- car boot sales take up a large chunk of your time. You have to set up early and come home late, which takes a lot more time than selling to WeBuyBricks.
