US coupons

Im going to the US in a couple weeks and was hoping to use lots of coupons for our groceries. Where is the best place to get coupons online? Will all stores take prinables and which is the best store to shop at? Can I stack in the US? Any info would be great. THANK YOU :biggrin:

coupons.com has good coupons.

I have a list of US grocery coupons (from the US Sunday paper) for trade here if you are interested. All I ask in return is the postage - either 1 stamp or $5 or so in coupons from my wishlist or 1 Stouffer's PIN. Or, if I have some Canadian coupons you can use and we work out a trade, I can just add the US coupons as a bonus.

For printables, here are some US coupon sites I know of:
redplum.com
smartsource.com

Also,if you check the web sites of brands you are interested in, you might find some printables - kelloggs.com for example has printables, and so does http://www.campbellskitchen.com/SavingsCenter.aspx .
