SwapASet

SwapASet is a membership marketplace where families and adult builders can exchange finished LEGO sets using Brick Credits. Members list complete sets, earn credits according to each set’s retail value, and use those credits to request another set in the same value tier or a lower one. The service offers a way to enjoy new builds without continually buying sets, with listings spanning themes such as City, Botanical, Star Wars, Technic, and Icons.

To list a set, members scan its barcode and confirm it includes all pieces, the original box, and its instruction booklet, which may be original or printed. The requester pays shipping, and SwapASet’s Complete Set Guarantee covers missing pieces, with replacement pieces ordered from LEGO up to $5 per swap. Browsing is free; the Swapper membership costs $4.99 monthly or $49.90 annually and includes credit earning and set requests. New members may qualify for up to 12 months free by posting sets, subject to a founding-member offer for the first 100 members.
