I pay about 95 cents to mail my grown up blocks out. I squish them as small as possible too. One of our post offices wants to charge me more then that so I go to my regular place. Sometimes it only costs me 65 cents. I think that is on the ones that do not have a lot of intricate pieces so not a lot of stitchin. But it seems it all averages about the 95 cents. It is strange how different the pricing can me even from teller to teller in the same post office.
