Terms of use

Last updated: July 2026

By using BrickMargin you agree to what follows. It's written plainly on purpose.

What this site is

BrickMargin publishes estimated secondary-market values for LEGO sets, calculated from public listings. It is a research tool, not financial advice, and not an offer to buy or sell anything.

Accuracy, and its limits

Values are medians of live asking prices, not confirmed sale prices. Real sales usually settle lower. Data can be stale, incomplete, or wrong — a listing can be mispriced, a search can match the wrong product, and markets move between our checks. Every value is shown with a confidence grade and a sample size so you can judge it.

Decisions you make with this information are yours. We don't guarantee any value, price, profit or outcome, and we aren't liable for losses arising from use of the site.

Accounts

An account requires a working email address. You're responsible for access to that inbox, since it's how sign-in works. Don't create accounts for other people or use the site to break any law. We may suspend accounts that abuse the service, and you can delete yours at any time by emailing us.

Acceptable use

Please don't scrape the site in bulk, resell the data as your own, or try to disrupt it for other people. Reasonable personal use — looking things up, saving sets, exporting your own data — is exactly what it's for.

Affiliate links

Some outbound links to retailers are affiliate links, and we may earn a commission on purchases made through them. This never changes what you pay and never influences a published value.

Trademarks

LEGO® is a trademark of the LEGO Group, which does not sponsor, authorise or endorse this site. Set names, numbers and images are used for identification only.

Changes

These terms may change as the site does. Material changes will be noted by the date above. Continuing to use the site means accepting the current version.
