is it safe?

I'm always "trying" to cut corners and save money where I can. (emphases on "trying" because splurging gets in the way.) So when I need to buy groceries, sometimes expensive name brands will push me closer to supermarket deals. I think this is something that I've learned from going to college and being a broke-ass frat boy. nothing like budding ham! HOWEVER, one would venture to question the quality of some of these cheap finds, which is why i'm questioning the Dollar Store. You know the Dollar Store -- they're all over the nation. Where everything in that store is ONE DOLLAR. and they have deals like 2 for TWO DOLLARS! what a deal!! but seriously, some of the items they have in there look pretty legit. I'm not doubting the store and the objective at hand here (that they're selling things at a cheap ass rate). What i'm questioning is how safe are these things or how long do they last for? If i buy it, do i have to use it right away before it turns into dust. Then i just have dollar dust (as opposed to Bill Gates' 100 dollar dust). And then they have some of the same things in the normal grocery store for more than one dollar. how did Dollar Store get a break from that food company to sell their food at only one dollar a pop? I mean...they have name brand stuff at Marshalls and T.J. Maxx cause there's a little deformation to it. "See this Sean Jean jacket I'm wearin?! Check it out...i'm hot...MAD HOT! but just ignore that orange paint mark on the bottom back and the hole up by the collar....s'all good...s'all good...." S'all TACKY, biatch! SO...is Dollar Store food safe?
