I have found another way of saving some money: soap sacks. Before, I used to buy body wash and body puffs for the shower. The body wash is extremely extensive: $3, $4 or $5 dollars. I like the lather that the body wash produced and preferred it to washing with a regular bar of soap, which was much cheaper. However, I came across soap sacks which are a nice alternative. You put the soap inside the sack and you can lather up the soap, creating as much lather as a body wash.
The soap also dries nicely in the soap sack which does not leave it soft and slimy as soap usually gets in the shower. Simply put, it allows me to enjoy the benefits of body wash at the cost of cheap soap. This is not the brand that I have (I bought a cheap version at Wal-Mart), but this ad will give you a general idea of what a nylon soap sack looks like.
