Brush Retail

Spanish vocab for clothing store, shopping, retail?
I just got a job in a clothing store where I am the only person who knows any Spanish and I may need to do some communicating in Spanish. I'm not fluent by any means, but I'm proficient. Anyway, I'd like to brush up on words and phrases I might use
sales and promotions (like _% off or buy one get one free), fitting room, more advanced clothing words, talking about sizes, talking about transactions, and anything else that might be important
Thanks so much
Here's a bit of what I find.
http://www.studyspanish.com/vocab/ On the left sidebar they have lists of vocab, some is free, some isn't. The free parts should help.

http://spanish.about.com/od/spanishvocabulary/a/shopping.htm This is more of the "how much is this" etc etc
ALSO go to livemocha.com and enroll in the FREE spanish lessons. Under Unit 2 Lesson 5 is more clothing. It allows you to play games too to help learn. Under Unit 6 Lesson 5 is shopping.
Hope these help and good luck
