The other thing I like about PP is the fact that when the auction ends, the item is typically paid for within 24 hours (many times within 30 minutes) and the item is out and gone.
With checks and MOs you have to wait around for the thing to arrive in the mail. If it's a check you have to make a decision as to whether or not to hold it for bank clearance (I don't). Meanwhile the item is still sitting on the shelf waiting to be mailed.
And... What could happen now is some newbie buyer could ding your "shipping time" star because he didn't like the fact it took him 4 weeks to get the item.
PP just speeds the entire process up.
Isn't it FUNNY how everyone here said they don't mind the PP fee, yet we bitch and moan about the eBay fee.
