I shop both for different things. I do wish Target carried it all, I prefer the Target experience. It feels cleaner, nicer. And when a Target & Walmart are right next to each other they keep prices competitive with each other.
Target for Huggies Natural Diapers, Huggies Natural Wipes, California Baby soap, Cliff Bars, fruit leather. I like their clothes too.
Walmart for Rice Milk, GF pasta, Earth Balance Vegan margarine, craft supplies, 100% cotton boys boxer briefs and Peaches & Cream yarn, boys jeans & shirts
Misc things past those mentioned like tolit paper etc I get at whichever I am at.
