Do you want to sell your old LEGO® bricks? 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® bricks. That includes a breakdown of all the best places to sell your LEGO® bricks and how to go about it.

Should I sell my LEGO® bricks?

Are you debating whether to sell your LEGO® bricks? 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® bricks.

1. More money

Selling LEGO® bricks is a great way to earn extra money. You could sell your LEGO® parts 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 it and getting nothing!

2. Better for the environment

Selling your LEGO® bricks 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® bricks also means that less new LEGO® bricks must 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® bricks on the second hand market reduces the need for production, saving plastic and cutting down pollution.

3. Declutter your home

Have tiny bricks taken over your home? Sell your LEGO® bricks 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® bricks you have left.
