With the rising popularity of apps offering to sell your used items or buy from someone in your area, it can be hard to find a quality site. FLIP, also known as “everyone’s sneaker connect”, is a fast-growing app where you can do just that. On FLIP you can buy and sell hard to find, lightly used sneakers at ease. Not only will FLIP buy your shoes if they don’t sell in 90 minutes, but they are the middle-man for all transactions, so everyone feels comfortable doing business. In addition, the sneakers are sold in an auction-like format, which guarantees that you’ll get the highest dollar when you are selling.
