Lol that's 5x more I paid in freight to ship my cast iron wood stove from the UK.
You could have them charge your UPS business account directly, which is my new preferred strategy. That way they can't do weird things with the numbers.
I don't recommend that. Yes, anyone can setup a ups or FedEx account. But as someone who used to do it it's not worth the losses.
The seller needs to be aware that they are loosing PayPal protections when they use someone else's shipping account. Basically, the shipping account on the label can "change the terms" and redirect packages, remove signature requirements, etc. This voids PayPal guarantees for the seller, as stated in PayPal terms the seller must use their own shipping account to qualify.
Also, it's up to you to file a claim about damaged goods - as it's your account. The Seller is off the hook, unless you can convince eBay that they purposely packaged it badly. After several claims I can tell you,
I don't want anyone boxing and shipping something on my UPS account. They could wrap it in aluminum foil and it'll be shipped, and UPS will easily deny the claim due to improper packaging - denying you restitution and leaving you SOL.
Tip for others reading this: always always always take a dozen or so pics of the box as you found it on your porch, opening it, and pics of your goods all the way around. For heavy equipment like "network equipment" and "servers" (quoting as UPS and FedEx define these in claims!), UPS and FedEx requires "double boxing", which no one hardly does! If not properly packaged, they will easily deny claims.
