If you haven't checked out coupons.com yet, I highly suggest you do so! You can print many money-saving coupons that can be used at a host of retailers! You can usually print two coupons per computer; just hit your back button after you've printed your first copy, hit reload/resubmit, and a second copy should print!
They add new coupons all the time, and they usually "reset" on the first day of the month. This means they will either remove the coupon entirely, or reset so you can print again even if you already have.
Some of my favorite coupons that are up right now are:
Hefty One-Zip Bags - Save $1.00 on 2
Nexcare Bandages - Save $1.00 on 1 (makes free bandages at Target & elsewhere!)
Old El Paso - Save 60¢ on 2 (makes for cheap taco seasoning packets!)
Keebler Wheatable Crackers - Save $1.50 on 1
Right Guard Deodorant - Save $3.00 on 2
Stove Top Stuffing - Save $1.00 on 2
Roman Meal Bread - Save $1.00 on 1 (let me know what store you find this in)
Sometimes it can be hard to find a specific coupon - what I have found works best is if you click the "category" on the left side of the page, then the coupons will be sorted by type of product.
