I have no shame in saying that I love Dollar Tree! My money is important to me and I can definitely make it stretch at the Dollar Tree. Everything is literally $1 or less. I typically only buy things like paper plates, aluminum foil.. everyday items that do not need to be name brand (they actually carry Reynold's brand foil, though - which is super expensive at the grocery store). I also buy a lot of plastic tupperware there - only $1, so if I leave one at work, I won't care!
Tip: Dollar Tree now takes manufacturer's coupons & they carry a lot of name brand items! And no, the products are not expired.
