I will bet that was an Amazon return. That was what was amazing to me and it has happened several times. As soon as UPS registers the return,which is very shortly after you dropped off the return, your refund is issued and your CC is credited before it is even shipped let alone received. So there is no need to take an Amazon Credit for a fast refund when you can get a cash refund extremely fast. There is no long drawn out delay. It is much quicker then getting a refund back to your card from Walmart or NAPA. Gives you the chance to try different things and sizes painlessly...Thanks,mjac
