Cold FX $2 Discount Coupon!
The coupon is valid for ages - until the 31st of July 2010!
I've seen quite a few Cold-FX coupons flying around the place from time to time.
If you manage to find a few different ones, you could even try out the process of coupon-stacking at your local London Drugs store! London Drugs is one of the few Canadian stores which accept multiple coupons on a single item.
