I just want to get this out there because it has happened twice to me in 3 months.
a customer bought a cd from me at 9:56pm Friday. I mailed the disc on Monday morning, and the usps carrier scanned it "delivered" instead of "pickup". The customer was able to open a not received case, even though it has not been a full business day since they purchased. It makes it appear as though I've done something wrong, and is frustrating that this is even possible.
