The most comprehensive listing of store coupon policies and price matching polices on the web!
Find your Grocery Stores Coupon Policy: Print them out and take them with you to the store when coupon shopping! Put them in your coupon binder so that you have them at the store if a cashier should give you a hard time or won't let you use a certain coupon.
Note that store coupon policies can change frequently and may vary state to state/province to province/city to city, even street to street. Check with your store first before assuming the policy posted meets your local store manager’s instructions to the store cashiers.
Do you know about the Scanning Code of Practice in Canada?
"If the scanned price of a non-price item is higher than the shelf price or any other displayed price, the customer is entitled to receive the first item free, up to a $10 maximum."
Some US stores follow a similar code - ask the checkout person, if your item is charged more than the displayed price!
