Shipping A Frame??

I think there is a surcharge if you ship UPS (maybe USPS) if it is not in a "regular" shaped cardboard box. Irregular shapes dont stack up well! You can ship not in a box, but it will cost a bit more. Also, if you are using a box, what dimensions are you using? If it is just barely meeting their "oversize" definition, by trimming the box down a bit might trim off a few bucks.

And those other guys offering to ship so cheap maybe simply eating part of the cost!
