I messed up and ordered a couple things I discovered were not what I really needed. Tried to cancel the order but a couple days later it got shipped anyway.

Can you just refuse the shipment to avoid having to pay postage back?

When I called about a similar issue they said I could just refuse it.

Just curious. Do stores have to pay return shipping charge to USPS when you refuse a shipment?

I *think* buy.com will make you pay for the shipping if you don't want it (unless you refuse it..which sometimes takes weeks to get back to them) ..read their webpage :P
