here's a few tips off the top of my head:
- pricematch!
- if you can get VIP SPC card, do it. totally worth the money. then use it at zellers and try to do as much shopping there as you can to get the discount.
- bring reusable bags. most places charge now. and zellers gives you HBC points if you bring a bag.
- mail in rebates. find them, submit them, be happy with your free stuff.
- obviously USE COUPONS. save.ca, gocoupons.ca, printables, of course you can get tons on www.thinkcoupons.ca ;)
- price adjustments. if you buy something for, say, 4.99 one week and it goes on sale the next week for 3.99, take your receipt to the store and get the difference! most stores do this.
- SCOP! pay attention at the register.
thats all ive got for now :P
