I ordered something off of ebay on 2/23. Paid for it immediately. Got the shipping confirmation without a tracking number on 2/26. I knew that they used 'brown' ground so yesterday (3/5) I visited the UPS site and discovered that their ship-time from the senders zip code to mine is 4 days. Something's not right!

So I sent an e-mail asking them for the tracking number. <disaster>They responded today stating that it was delivered on 3/2!</disaster>. Left on the front porch is the official note. I went home from work today just to check all around my house, again! No package!!

I've sent two e-mails to the sender (a real dealership in MN not just a person selling) and so far haven't received a response. I'm a typical 'men are from mars' person and having this unresolved without any idea of what is happening is driving me crazy

My question is this - Since I know that this isn't necessarily their fault (probably the truck driver losing the package) how long should I wait for a reply until I start disputing charges with paypal/my credit card?
