For those who like this product, Colgate Optic White and Renewal toothpaste is a $1.84 MM at Walmart using Ibotta, Coupons.com and Shopkick.
Ibotta rebate: $3.00
Coupons app: $3.00 through Nov 30
Shopkick: $2.80 (700 Kicks)
There are two unique Ibotta rebates and app coupons, so the deal could be done twice if Shopkick quickly resets after the first receipt.
There is also a $2 paper coupon exp. Dec 4 that could be used instead of the Coupons app for an $0.84 MM.
