I just wanted to double check. Can you send a letter that requires more than one stamp to RTC? My kid is in RCU with an injury and will be there a couple more months. He is desperate for things to do and read. I'm happy to enclose some puzzles, questionnaires, magazine pages from his favorite mags (appropriate ones, like Scuba etc) and that sort of thing. His Dad had a couple envelopes that were just over an ounce and put a second stamp on them (in #10 envelope). Is this going to be a problem?
I really thought I saw something about this on this site before and haven't been able to find it specific to the number of stamps used. Thanks!
