Walmart does give overage, but they might need to redirect you to the customer service. If they don't allow it, kindly remind them of their coupon policy which clearly states:
When coupon value exceeds the price of the item:
• the excess amount can be given as cash or can be applied toward the basket purchase, at the customer's choice
Edit: Thanks to deadice for mentioning that there's a $1.00 cashback on ALL Vick's products on Checkout 51 (app, on Google Play & App Store). There's a limit of 1, so you can only use it once.
