STYLETHREAD -- LET'S TALK SHOP!

I am beyond pissed.

I ordered my wedding shoes from Pearl's Place (a shop in LA) that everyone raves about.  They quoted me $100 ($20 below retail) and said I should have them in 4 wks at most.  I totally spaced asking how much shipping was, and then couldn't get through on the line again to ask.  I researched what people who ordered from PP had paid for shipping and it seemed reasonable, and emailed to inquire and was told $12. 

I got my CC statement - complete with a $120 charge from Pearl's Place!  They charged me $20 to ship my shoes, and I haven't even received them yet 4 wks later!  If that isn't bad enough, I could have ordered from another company including 2 wk shipping and paid $110.

What can I do now?  I emailed them to verify what they normally charge for shipping, and if I have to I'll attempt to call (their phones are just impossible).  Do you think if I refused the package they would take them back and credit me?  Or possibly credit me a portion of the shipping costs?  $20 just seems sooo exorbitant - that's more than most people paid to have their dresses shipped from Pearls!

ETA:  So they replied and verified $12 for shipping, so I'm assuming the extra $8 they left off my total when I ordered was taxes?  Waiting for another reply ....
