I work out of two different offices, and as luck would have it, there is a post office a couple of blocks from each. Whichever office I go to that day, I have a post office I can visit on my drive in.
Because of that, everything that everybody gets from me in a trade is done from a post office window. I wouldn't want someone to have to pay postage due on an arbitrary decision made by somebody at the post office while I'm not standing in front of them to pay the bill.
I love to trade! Check the top couple of paragraphs of my profile to see my general trading desires. If you're uncertain if I’ll take a certain trade, message me and we can figure out something.
