I use to print all of my postage. For domestic letters, I print the addresses, and postage directly on a size 10 envelope. International mail is currently being printed on a sheet of NetStamps. This will allow me to print an envelope with my return address, and then I affix the postage stamp (with the correct amount), and drop them off at a mailbox. basically makes it more convenient to use them, and pay the high price with them, and helps with my agoraphobia as I don’t have to go to the post office and wait in line for postage stamps. I pay on the 2nd of the month. My postage is taken out of my discretionary spending.
