Walmart's Coupon Policy

I have been hunting for Wamart's coupon policy for quite some time now! Here it is straight from their website:

Walmart accepts the following types of coupons (see guidelines below):
•Manufacturer coupons (Cents Off)
•Free merchandise (or manufacturer's Buy-One-Get-One-Free) coupons
•Store coupons
•Pharmacy (Advertising and Promotional) coupons
•Internet coupons
•Soft drink container caps

The following are guidelines and limits:
•Walmart only accepts coupons for merchandise we sell and only when presented at the time of purchase.
•Coupons should have an expiration date and be presented within the valid dates. Walmart will not accept expired coupons.
•Internet coupons should be legible and say "Manufacturer Coupon." There should be a valid remit address for the manufacturer and a scannable bar code.
•Only one coupon per item is permitted.
•Use of 40 or more coupons per transaction will require approval by Customer Service Manager.
