Today I sent my fiance to weigh and get stamps for our invitations.I also asked for stamps for the rsvps. Our invitations cost 1.08 to send each so he bought a LOT of .64 and .44 cent stamps. He didn't realize until he got home and had already bought the stamps he had bought enough of the more expensive stamps to put on the rsvp's instead of normal stamps. Would it be weird to use the .44 or .64 cent stamps on the rsvps instead of being stuck with a lot of unused stamps and have to go out and buy a lot more?
