Frequently asked questions
Is BrickSense free?
Yes. The extension is free in the Chrome Web Store and on Firefox Add-ons, and the set pages on this website are free to browse.
Which shops does it work on?
Any website that shows LEGO set numbers, such as online shops and marketplace listings. There is no fixed list of supported shops.
Where do the prices come from?

Does BrickSense read the pages I visit?
