How long should you wait for the seller to deliver a product before you cancel the charges on your card? It's been about 2 weeks since the auction ended...last week the guy claimed he was sending it out on Monday (Sept. 25) using 2 day delivery. I contacted him again, but he said he's been having problems with his email so he can't respond immediately. Should I bother waiting for a response or just cancel the charges on the credit card and buy somewhere else?
