My small town post office only has flat rate priority mail boxes, so I have been having to go into town every so often to pick up different sized priority mail boxes. I like to get #4(7x7x6) and #7(12x12x8). Well now the in town post office says they will only be carrying flat rate boxes from now on! Are post offices across the country doing this now? Do some of you order boxes? I may have to go to that.
