Consider yourself warned
So a couple years ago I used FedEx for the last time after they lost a Porsche targa top I had sold (they didn't even have record of it leaving the facility I shipped it from, but it wasn't in the facility either

) Anyway, I swore them off for good when they essentially screwed me on my claim and it took months to get it resolved. Shipping isn't rocket science, but they can manage to F it up pretty good.
(insert fool me once, fool me twice quote here)
So Kodiak Wheels in Canada used FedEx to ship my wheels. I shoulda asked who they were using and didn't think to do so. Well, first they damage one of them. I filed a claim starting on 9/9/07 (which still isn't finalized!!!) and then the next day, 9/10/07, they charged $127.59 to my credit card!
It has been two months of being transferred, hung up on, etc and ultimately this morning I was told that billing had no record of the charge and I would have to file a dispute WITH MY CREDIT CARD COMPANY. That's right folks,

FedEx CANNOT CONFIRM THE CHARGE AND DON'T EVEN KNOW WHY I WAS CHARGED, BUT WON'T CREDIT MY MONEY. I have to go through a dispute claim with my credit card company now, which will be another month I am sure.
HEED MY ADVICE, DO NOT USE FEDEX. That is about 3 warnings now

Not to say I haven't had issues with damaged packages and UPS, but UPS has ALWAYS paid the claim or took care of any issues immediately. They tend to cost a little more than FedEx but the money is well spent for the level of customer service. F('ing)edEx may call the dept customer service, but they have no idea what that is.
At the hot rod shop I worked at years back I was in charge of shipping among other things and kept track of the shipment qty v. claim qty and FedEx lost that battle too. We used UPS exclusively at one point and would only use FedEx if the spot was so rural that UPS didn't go but they did or something similar. I broke down and used FedEx for the targa top only because they were right around the corner from where I lived and I wanted to get it on its way to the buyer - shoulda taken the time and drove the 10 miles to the UPS drop point.
