i kinda doubt they went in an raised the prices just because you qualified for free shipping

sounds like it was going to happen regardless of whether or not you were online and you just hit the sale at the wrong time.

only thing i can suggest is... well it's too late now but calling up to order via the phone and trying to sweet talk the operator into letting you have the sale still

a computer would say "no" but a person might say "yeah, here's the sale price"
