It's all in the interpertation of the regulations. I just sent off all the mails for 45 each (except Canada), but if it were a different clerk I'd have had to pay for parcel post since they know it's more than paper inside (they know me too well
-also my 5th boom) Received 2 in today's mail, no problems
When sending the finished blocks I use the manilla business sized envelopes and try to stager the seams to get a good postage price.
