Thank you all.

This is fantastic advice. The fact that the post office still charges for this stuff, when it's free online is outrageous. (No wonder they're going broke!) Of course even more outrageous is the fact that I didn't do my due diligence and find out about these other great options ahead of time. saving $0.85 on every shipment is HUGE!

I appreciate all the wonderful people and great advice on this forum. Thanks again!
