I have used this store two or three times for shipping pre paid Amazon returns. No fuss no muss with a receipt issued by store that the package was shipped.
Last Monday however I made the mistake of dropping off the package to the person closing the door. Since it was closing time I didn't ask for a receipt... Big mistake as the package was never shipped... And there is no receipt to tell Amazon that I did ship the package.
Disappointing ... Beware of not getting receipts at this store for your shipments!
