Nonetheless, it's what I expect and receive from other suppliers. It's a trust issue - I trust them to bill my credit card and supply the correct goods; the suppliers trust me to pay the bill and return erroneous goods. I feel I'm on a stickier wicket with stuff that I've ordered in error; however, most that I've used will accept things back without much trouble. Some charge a restocking fee.

The only time I've been tardy about returning an item in that scenario, I received a call a little while after to remind me. Oh - and I *always* get a certificate of posting nowadays, so still have to go to the post office.
