CVS does not have a published coupon policy. However, here is an email that was received in response to their policies. Feel free to copy and print it and have it with you when you go shopping at CVS
Thank you for your e-mail regarding CVS/pharmacy coupon policy. Unfortunately we do not have a copy of the policy to distribute to customer. However, here is a rundown of the most frequently asked questions.
Our registers are set to allow one CVS coupon and one manufacturer coupon per item. However, the staff should be allowing customers to use Extra Bucks in combination with other CVS coupons since these are coupons you have “earned.”
In addition, they should be allowing the use of one “offer at the register” coupon which would be an open offer of $3 off of $15 or a certain dollar amount off of a specific item. Since our registers are programmed to only accept two coupons (one CVS, one manufacturer) per item if the number of coupons exceed the items purchased a member of management will need to assist the cashier in processing the coupons.
CVS/pharmacy will accept coupons printed from the Internet. They must have a legible barcode that scans at the register. If the coupon does not scan at the register, the cashier should politely inform you that we are unable to accept your coupon. We do not allow manual overrides at the register for coupons printed from the Internet. CVS/pharmacy will not accept offers printed from unauthorized internet postings or reproductions, copies, or facsimiles.
CVS/pharmacy does not accept competitors coupons.
When an item is on sale for buy one, get one free and the customer has a buy one get one free coupon for that same product, the coupon will be accepted and both items will essentially become free (plus any applicable sales tax).
Also, two manufacturer coupons can be used on a buy one get one free purchase as long as two items are scanned at the register. The system logic sees two items scanned and will allow two coupons.
