Mostly agreed with above sentiments, regarding UPS, tire rack and so on.

Avoid UPS unless tirerack. USPS, DHL, FedEx... in that order, in my experience.

Can you drive to the airport to pick them up? If so, you can self-clear and pay no brokerage fees, just duty and/or tax depending on where it was manufactured.

Or, I've had luck refusing to pay the brokerage fees when UPS/FedEx bills me and wait for it to go to collections. Then I phone the courier and complain I wasn't given the option to self-clear, and didn't want to pay for them to do my paperwork. They've always settled for the cost of the excise/duty/taxes.
