I frequent both places. Walmart more for food and household items. Dollar Tree for cleaning and what I call "temporary" items. Things for my kids that they will break easily.
Don't get me wrong. I love the dollar store. I'm sorry, but a place where you can get 32 things for 32 dollars and tax. Perfect. I love the dollar store, and while I confess I have 2 things on this list, I didnt realize the other items can be bought for a dollar.
