Looking for a good coupon site

I heard you can download grocery coupons so I am looking for any good sites to download them. I found a few but they all have the same coupons. Is there any that I can download any coupon by searching for what I need and just print it out?

Any help appreciated.

I'm not a coupon cutter, I'm more of a shop the sale papers kinda gal.

Shoplocal.com has all your local sale papers online. If you go to walmart they will honor ANYONES sale paper price so you can do your shopping all in one location.

Slickdeals.net has coupons and is great if you're looking for like a 15% off JC Penny or Sears coupons.

Hope that helps some.

It appears however that grocery stores- particularly Walmart- will find any excuse in the book NOT to honor these though.  I recently tried to use them at Wally World and the cashier told me they were "fraudulent" b/c the city name on the coupon said "Del Rio, TX".  She went on saying how the FBI (seriously ha) came in and trained them all on it.  She said that "all legit manufacturer coupons- the "real" ones in newspapers/mags have 'San Antonio, TX' on them."  Every "real" coupon I've looked at since has "Del Rio" on it so apparently, the cashier was just being lazy.
