Walmart sells Oui by Yoplait [ouibyyoplait.com]
(yogurt) for $1.34 (by me at least, shoreline CT - not sale price but regular price). ibotta has a $1.50 rebate each (only at WM), up to 3 per receipt.
So, best case you get 3 of these for -$0.16/ea; worst case they are FAR (if ibotta corrects the rebate to the lower sale price).
There is also a "generic yogurt" $0.25 rebate which would sweeten the deal. (possibly expired)
