Okay, hindsight is always twenty-twenty, and all future shipments will include delivery confirmation. However, my mother did me a favor and shipped two packages via USPS parcel post last Tuesday. One item (the one with insurance) arrived over the weekend (Dallas to Michigan). The other (without insurance) has not arrived in California, and the buyer is getting nervous. I have the receipt from the post office, and it notes the zip code, weight, price, etc. However, I have no tracking method. How does Paypal handle issues like this if the buyer disputes the charge. I feel terrible, and I really hope it got there last night or arrives today.
