I couldn't find this on the Ibotta Community, so I thought I would post it:
Mentos Gum sells for $3.12 at Walmart. The Ibotta rebate is $1.00. There is also a 10 kicks ($.04) for a scan in store and a 150 kicks ($.60) for submitting your receipt to ShopKick.
Your final price is $1.48, which is more than 50% off.
