Get in touch

One person builds and runs BrickMargin, so replies are not instant — but every email is read, and reports of wrong data get looked at first.

A price or a deal looks wrong

This is the most useful thing you can send us, and we would rather hear it than not. Include the set number and, if it is a deal, a link to the listing. Nearly every improvement to how we filter listings came from someone pointing at one that should not have been there.

Worth knowing what we already exclude: parts lots, single minifigures, individual floors of modular buildings, light kits, instruction manuals, and listings where the seller flags damage or asks you to read the description. If something slipped through anyway, tell us — that is how the next filter gets written.

A set is missing, or has no value

We track thousands of sets and price the ones with enough live listings to be worth publishing. If a set has no value shown, it usually means too few listings exist right now rather than that we have missed it. Send the set number and we will check.

Your account

For sign-in trouble, a verification code that never arrived, or to have your account and data deleted, email from the address on the account so we can be sure it is you. Deletion removes your watchlist, collection and profile, and it cannot be undone.

If a code has not arrived, check junk first — BrickMargin is a young sender and filters are cautious. Signing in with Google skips codes entirely.

Business

Data questions, partnerships, or press: same address, and mention what you are after in the subject line.

What we cannot do. We do not buy, sell or value sets on your behalf, and we cannot advise you on what to do with your money. Everything on the site is measured from public listings and published with the sample size behind it so you can judge it yourself.
