I gotta disagree with you guys on this one--to some degree.
That is, I've got a guy who royally stiffed me on a refrigerator and refused to help me--but helped a lot of other people out in their claims with the shipper.
He "stiffed you" by not sending the product?
Or he "stiffed you" by sending the product and then not helping you out when the shipper lost/destroyed/stole/misdelievered the product?
I need more details to make a judgement on this, but if I sold something, shipped it out and then something happened between the buyer and the shipper, I'd be pretty pissed that I had to refund the money for it.
Okay, here's the story a little longer; was trying to be brief for the forums.
1) Purchased item. Paid immediately; always do--have a long time 100% and am proud of it. Don't purchase unless you can afford the product, I always say.
2) Followed-up many times. Took over 10 days for item to ship via FedEx--claimed "bad weather" in Macon, GA. Try living in Chicago for some bad weather, and our shippers didn't have many major problems...
3) Received item on December 23rd. Was out of town, but neighbor helped FedEx driver with the package into my garage. Neighbor is a close friend, was very, very careful with the item, as he knew what it was and the intent and how much of his summer would be spent tapping from it for free.
4) Opened item upon return from holidays. Lots of major dings, scratches, broken parts. Contacted FedEx and explain situation. They "insure" for up to $100 on a shipment. I paid an extra $6 for insurance that was never applied. They say I need to contact the seller.
5) Contacted seller for assistance; claims need to be filed with FedEx and he needs to fill out a waiver so FedEx can deal directly with me, including sending me funds for the damage. No response.
6) Contacted seller again. Gets hostile and asks me what I want from him.
7) Explain to seller what I need from him--the waiver.

Seller claims to not have a fax, please supply with an email address to send form to FedEx.
9) FedEx doesn't do email.
10) Contact other people seller has sold to that have filed claims, based upon their own feedback of seller. Oddly enough, seller responds quickly, including faxing to FedEx. Things seem to go smoothly for people who just aren't me--and I've not been a jerk, just matter-of-fact.
11) Seller doesn't respond to 2 more emails.
12) File claim with PayPal and eBay.
13) Seller claims he's offering a full refund if I ship it back. Oddly enough, PayPal sends a note with the same request.
14) Explain to seller that I'd prefer not to ship back but to just get this waiver business out of the way. Seller explains he wants HIS property back and he's tired of jacking with me, will deal with PayPal.
15) Contact PayPal again, PayPal has already done a temporary hold on the full refund of the funds. Which is about $110 more than FedEx would have given me. PayPal says to return the item, with tracking information, to address provided. PayPal claims that this person is a business and does a lot of transactions and that they find it very hard to believe he does not have a fax machine.
16) Funny thing, seller only provides PO Box address. Item is too heavy to ship via USPS, so have to go through entire issue to get street address so I can use a different shipper. 84lbs, not the 69lbs claimed to FedEx.
17) Shipped back via UPS. In same packaging it came in--which is retail packaging. UPS shipper agrees with my assessment that this person bought a crate of these mini fridges from Lowe's and then shipped them in the same boxes that were meant for retail selling--not for shipping. 1/4" of styrofoam ain't enough to keep these safe no matter what.
18) Contacted FedEx again to explain situation, what's happening. Gave tracking number. Brother-in-law works for FedEx and contacted him; lots of claims from this guy on virtually the same items. It's interesting and the account is flagged.
19) PayPal issues full refund. All of which could have been avoided by a fax to FedEx allowing them to deal with me.
You can make your own assessment from that. I spent too much time on it, but the end result is fine by me--with the exception of the loss of time for a project. That stinks.
