CORRECT POSTAGE for a padded priority mail envelope is $6.80. Today I have discovered THREE envelopes short of money for return of your blocks and at least one mailed to me at the wrong rate. I don't want to think that our blocks could end up in some kind of mail purgatory because of being $.35 short when you ship to me. I really do expect everyone to send the correct amount and ship correctly to me. Thankfully, quite a few of you have sent $7 for shipping so I've got a bit of a slush fund I use to defray, not cover, my expenses which include labels, tape, ink, gas driving to the PO and shops for supplies/shipping when needed, etc. I know it may seem like a few cents here and there, but PLEASE put the correct amount on, and in, your packages. Seriously, folks! Thank you!!!
