I am finding that more and more ebay sellers are saying that their post offices won't allow them to stuff flat rate envelopes. I've not had that problem with my post office, which is on the picky side-I have to add extra postage if I send a tiny handmade button in a letter! :roll:
I'm wondering if this is becoming a regional thing, local only, or does the seller just not want to stuff? Have you ever not been allowed to send a stuffed envelope?
