Ok, so when the OS3 rate was mentioned I ran the numbers at the UPS site, and it does come out to about that much if the box is big enough.
Phantomcow, your wheels should not cost near that much to ship, esp. over that distance. If you go to the UPS or FedEx site you can calculate shipping, they also list what makes a package be "oversized." You might want to check and compare your box to those so you don't end up in a situation like I am.
