Fabric Softener
Avoid buying fabric softeners at the dollar store! The truth is that you can get them for four times the amount at the same price if you go to Walmart and Target instead. A coupon can get you even further.
Sunscreen
Sunscreen from the dollar store is pretty useful. You can try to put it on your body, but you will still get burnt. This is because a lot of the products are near or past the expiration date already.
