Check the Walmart app for a clearance price on a tube of Colgate Enamel Health Sensitive Toothpaste. My app showed me an in-store price of $0.75. The actual price at my store was $2.50. I showed my phone with this item pulled up and requested a price match from the cashier. Since Walmart does price match to Walmart.com, the cashier honored the $0.75 price. I used a $1.00 coupon from the 2/4 Smart Source newspaper insert and scored a $0.25 moneymaker!
Also, readers have reported that some stores are not giving overage as cash. Again, it is Walmart policy that overage is paid out. However, to avoid any issues I recommend purchasing other items to absorb the overage in the total of the transaction.
If your store does not have the Colgate Enamel Sensitive Toothpaste deal, use a new $0.50 coupon that does not have any restrictions on which variety you purchase. Several other Colgate toothpastes are $1.67. Apply the coupon and pay $1.17.
