Did you know that you can print some store coupons online? Many stores have coupons on their websites that are not available anywhere else. (Remember, store coupons can be used in conjunction with manufacturer's coupons.)
Target (this is a coupon generator from OrganicGroceryDeals.com - scroll down and you'll see the area where you can choose how many of each coupon you want to print)
Walgreens (only a few are store coupons - they say "Walgreens" on them)
At Fred Meyer there are kiosks located right inside the grocery entrance (huge yellow ones) where you can print in-store coupons valid for one day only. These vary all the time, but it's worth checking into!
