# Brickfact

> Brickfact compares LEGO® set prices across retailers, tracks what sealed sets are worth on the secondary market, and publishes buying guides, set rankings, brick-brand comparisons and original price research. A collection tracker, shared with the Brickfact app, follows the value of the sets people own.

LEGO® is a trademark of the LEGO Group. Brickfact is not sponsored, authorized or endorsed by the LEGO Group. Some retailer links on Brickfact are affiliate links.

Prices follow the regional site: USD on https://brickfact.com, GBP on /en-gb, CHF on /de-ch and EUR on the other regional sites. The figures on a set page mean different things:

- Market value: what sealed copies currently trade at on the secondary market, measured daily. It is a measurement, not an offer, and it does not exist for every set.
- Retailer offers: feed prices for new sets from shops in the region. Unknown shipping is not free; compare known delivered totals and check the feed update time.
- Part-out value: what the individual pieces would fetch if the set were broken up and sold as parts.
- RRP: LEGO's recommended retail price.
