there is no $25 off $100 email, for use in B&M. If i were u I would make the order online using the code- but dont complete the order, just get to the confirmation page showing the CDRW and the $25 coupon, print that out, and take it in, that's what i do.
that way they have a peice of paper to put in their file ot whatever. if needed make up aomething about being out of stock online, that's why you came to the store.....
hope helps.
