i would have called them- and probably cancelled the order unless it was something i absolutely had to have----- one of the reasons i try to always shop at places that give me free shipping when i spend a certain amount---usually $35- $50 which i can always spend- then i don't have to worry about it-
i have found that some shops seem to advertise pretty good sales- and make up for it with high shipping rates- which i pretty much refuse to pay- it's not a sale if when you add in the shipping it would cost more than you can find it elsewhere....i would call customer service and talk to them personally though-to give it a chance to work something out- if that does not work though i just make note to not visit their site any more.
