MAC.BID buys returned and overstocked goods by the truckload from top retailers like Amazon, Target, Walmart, Home Depot, and Wayfair and resells the items through their proprietary online auction platform. All products are put up for auction with an opening bid of $1 with no reserve price. Winning bidders can expect to save up to 80% off retail while having fun participating in the online auction. In addition to its auctions, many MAC.BID locations offer Yinz Binz, a bins-style shopping experience where bins are restocked at the beginning of each week, with prices gradually dropping throughout the week.
