(no subject)
I'm about to ask a stupid question, but I honestly have never dealt with this before. I'm sending three holiday cards out of the country (two to Canada, one to Sweden). Where do I place the airmail stamp? Do I place it in the upper right hand corner of the envelope next to the regular postage stamps? I went to the USPS website, but I couldn't find anything that told me where I place the stamp on the envelope.
