We don't have Dollar Tree where I'm from, but looking at the food and drink section of their website, I'll probably buy Frosted Flakes, Cocoa Pebbles, and 2 cartons of milk. I love breakfast food.
As a foodie, i would buy alot of food and am not tired of eating, i would buy alot of juices, soft drinks and cakes and don't forget my noodles, i don't joke with that.
I will buy food or other kinds of stuff that I will need which is quite a good price than those other big stores. It can be batteries, something for beauty stuff, food, or the crafts area.
If I had $5.00 to spend at Dollar Tree, I would buy a variety of snacks and drinks. For example, I would buy a few bags of chips, a box of granola bars, a few bottles of juice or soda, and a few packs of candy. This way, I would have a variety of snacks and drinks to choose from.
