This is Walmarts Coupon Policy in regards to competitor coupons:
Competitors' coupons - A specific item for a specified price, for example, $2.99
- Buy one, get one free (BOGO) coupons for items with a specified price
- Have a valid expiration date
- Are acceptable in black and white
Enjoy!
Below is a list of stores to consider for Competitor Coupons--YMMV-- - Ace Hdwe. Ace Hardware Stores | Browse for Hardware, Home Improvement, and Tools. Thinking at the few times I've seen a Ace Hardware Ad it may be possible that they have the right kind of coupon that Walmart would match on occasion.
- Bloom/Food Lion Save with Quality Healthy Foods at Bloom Food Lion **I have no idea if they will have applicable coupons**
- CVS Online Pharmacy for Prescription Drugs - CVS Pharmacy Drug Store
- Dollar General Dollar General | Save Time. Save Money. Every day! **Dollar General does have coupons sometimes that will be acceptable**
- Family Dollar Family Dollar
- HEB grocery stores (located in TX) NOT HEB brands, MFQ only
- Home Depot Home Centerhttp://www.homedepot.com/
- K-mart Clothing, Toys, Electronics, Jewelry, Jaclyn Smith - Kmart.com
- Lowe's Home Center Lowe's Home Improvement: Appliances, Tools, Hardware, Paint, Flooring FYI Lowes have there own "manu" coupons but these barcodes do not work at Walmart as a manu coupon...so expect this to be YMMV.
- Office Depot Office Supplies: Office Products & Office Furniture at Office Depot
- Office Max Office Supplies, Office Furniture & Office Technology at OfficeMax
- Rite Aid Rite Aid : Weekly Circular
- Safeway Safeway - Official Site
- Shoppers Food Warehouse (SHOPPERS -- Low prices. Every day.
- Staples Office Supplies, Printer Ink, Toner, Electronics, Computers, Printers & Office Furniture | Staples®
- Target Target.com - Furniture, Patio, Baby, Toys, Electronics, Video Games Target.com has coupons. Manu ones Walmart will accept. It is extremely rare for a Target coupon to be acceptable due to Walmart's rules.
- Wegman's Wegmans. Also sign up for "Fresh News" for E-Coupons/Store Coupons. See home mailers.) **I do not know if Wegman's coupon's will be acceptable due to Walmart's rules. Input from our Walmart peeps would be helpful

Whole Foods Market
http://www.wholefoodsmarket.com/or pick up their Whole Foods Deals Coupon Booklets in stores. It is very likely that products sold at Whole foods are less likely to be sold at Walmart. So expect this one to be a huge YMMV and I have no idea what there store coupons look like.
