Premise: There are always diamonds to be mined at yard sales. The trick, of course, is finding them. The competitors in ``Flea Market Flip'' are asked to perform that trick, then they're challenged to refurbish or reinvent the items they've purchased in the hope of reselling them for a profit. Grouped in teams, the contestants in each episode are given a budget of about $500 to hunt for project pieces with potential. The team that does the best job of flipping trash for cash wins $5,000.
