Currently I use emeals to create my grocery lists for what I am buying at Walmart. They too have an integration to auto-link to Walmart Grocery. However, with their app it loads my grocery list in and automatically searches one by one for each item. I'm able to look through the list it generated for each searched grocery item, and add to my cart the exact item I want. This would be great for Ibotta, as it could automatically search and pull the name brand item, with the correct sizing/amount, and I could add it to my cart. Additionally, if the rebate is on any brand of an item, like it was for bananas recently, it would search just bananas, and I could pick which one I wanted to add to cart.
I very much recommend the Ibotta developers to look at how this works with emeals/Walmart Grocery integration, as it would be a wonderful compliment to the current Ibotta/Walmart Grocery integration.
