While I was making the pickup at our local UPS Store, a customer came in with an Amazon return with no label. She had a QR code on her smartphone, which she held for the clerk to scan so that a return label could be printed. I had never seen that and asked her what it was. I was really impressed. The clerk then helped me load the pickup pieces and I asked him about the QR code. Turns out that the UPS Stores have an exclusive agreement with Amazon to process these returns and are paid for their efforts. Has anyone else seen this?
