I am a checker at Safeway and this is our policy on internet coupons:
Printable internet coupons are defined as on-line print at home coupons that consumers receive via retailer, manufacturer and legitimate coupon websites. They typically require shoppers to register on-line to use the coupon, and shoppers are limited to 1 (sometimes 2) print from their printer.
In order to insure that we accept only legitimate printable internet coupons, Safeway has adopted the following store policies and guidelines:
*Do not accept coupons that do not have a manufacturer's bar code or manufacturer's redemption instruction.
*Accept printable coupons only if they scan properly at checkout.
*Do not accept more than one copy of the same coupon per customer.
*Do not accept coupons for free product (other than buy one get one that requires a purchase of the like item)
*Do not accept coupons for more than a $5 value or for more than 50% of a products retail price, whichever is lower.
*Do not accept printable internet coupons that do not have an easy to read expiration date or that extend more than twelve weeks. Most internet coupons may expire 30-45 days after you print them.
*Do not accept coupons that appear out of proportion or blurry, or are obvious duplicates.
Coupons may be rejected if they appear to have been altered in any way. Printable internet coupons are nearly always printed using the same technology and therefore have a standard format, with very specific security features, including a unique serial code.
To verify if an internet coupon is valid, see your Front End Manager. Printable internet coupons can be checked for validity at
