The following links are to some pretty good coupon sites. You may have to register (I know for sure Mommy
Saves Bigs requires registration)but I have not had a problem with unwanted email from any of the sites below.
Keep in mind that not all Super Markets take on-line coupons. They do out in the boonies where I live so it shouldn't be that much of an issue. If in doubt check with your store first.
You'll just need a printer for the grocery coupons. Others like at PromotionalCode.Com provide a code to use. This is great for on-line purchases and I have used these codes many time for Barnes and Noble on line with great success.
MommySavesBig has coupons for Ruby Tuesday, Coke products, Ann Taylor, Borders and Old Navy to name a few.
Coupons.com this site has grocery and sundries coupons. Current sample deal: $1.00 off any size (except 20 and 25 ft) Reynos Wrap Foil. Sample Deal:$2.00 Off Any Neutrogena Therapeutic Haircare Product and much more.
Coupon Cabin has discount codes for on-line purchase at well known stores such as Target, JC Penney and more. Also to many on-line retailers, like Zappo's and Overstock.com.
PromotionalCodes.Com offers discount codes on on vacations, cellular service, Norton, 1-800-Flowers and much more.
