There are a few reasons why this might happen. You might have purchased or attempted to claim the wrong brand, kind or size of a product (like buying a 12-pack of soda instead of a 6-pack). Sometimes there are minimum quantity requirements that will be noted in the description of the offer. Accordingly, if you do not purchase the required minimum quantity, the offer price will not apply. If you have questions, please check with the store associate at the Customer Service desk. Or you can call our Customer Support Center toll free line at 1-877-258-2799; they can look into your transaction to determine the problem and propose a solution.
