I had a great experience with Go Roostr. I was going to trade in my old MacBook using Apple’s official vendor for $100 store credit. On a hunch I googled other options and saw the great reviews for Go Roostr. I went to their site, plugged in my MacBook’s information and discovered they would pay $150- sent as a check. I printed the free shipping label, and spent $8 at the FedEx store to package it correctly with bubble wrap, but I came out $42 ahead of Apple’s offer. GoRoostr was quick in processing my trade-in. They mailed a check on the day they received it at their facility. Everything worked out perfectly, and I would use them again in the future.
