Best places to coupon shop in Surrey? G. Timbers/Newton/Guildford etc

I'll be visiting in July, and besides doing some LD shopping, i want to try and find coupons

I'll be in Green Timbers for the 2 weeks.

What are the most reliable places to try and get a few coupons in surrey? :)

Oh, and i almost forgot! does SOF actually stack now? how's service at the one at fraser hwy and 152?

Yes they stack and I haven't had any problems. Only used stacked coupons a few times though. I really haven't put them to the test with a huge shop and a ton of stacked coupons. That store only also PM Safeway only.
