What Products Will You Only Buy Name Brand? When I go grocery shopping, there are plenty of items that I have no problem buying generic versions of, but sometimes you just have to have that brand name product! Yesterday, Brain revealed to me that he is a bit of a ketchup snob! When it comes to ketchup, he will ONLY eat Heinz. Ketchup all tastes the same to me, so I don't really care for one brand or another, but there is another product I will only buy one brand of! If I'm looking for pepper jack cheese slices, I will ONLY buy Sargento. If they're out, then I go home empty handed. I've tried all the other brands, but Sargento has the best!
