The Body Shop scrubs are $16, I think, but they can last a looong time. And they always have excellent sales, where you can get them for less than $12!
The Got2Be scrub, and another one I have (can't think of the name) are HUGE and less than $10 for a tub and tube. I'll find the names - they're drugstore brands. Plus, I'll find my recipe for an at-home brown sugar scrub that's every bit as effective as these pricey ones - plus, it's edible! LOL!
