Meijer, Target and Walmart are in close proximity to each other in my neck of the Midwestern woods that I can do the rounds at for Ibotta deals.
My top three are Walmart, Publix and Sprouts.
Walmart has the most Ibotta offers that I use regularly. Publix BOGO's & Sprouts free items. (Didn't even know about Sprouts until Ibottta & now it's top three!)
Publix Target and 3rd place is probably tied between Whole Foods and Sprouts.
We’ve got Walmart, Target & CVS. There are others but I’m not a big fan.
