You probably have mentioned this before but I find some fabulous deals in the clearance section of many stores (like CVS, Rite Aid, Walgreens etc). Many times, there will be a shampoo, moisturizer, etc.. marked way down and if you have a coupon... you can get it for free or close to free. I have my standards though. I won’t purchase any sort of product that appears open or used. Sometimes you have to dig a bit too. I found a hair shampoo for treated hair that retails normally for $8.99. The price was $1.99 and I stocked my shelves with six. I didn’t have a coupon but it was a great deal. Just a thought.
My body wash which I get for FREE also serves as shampoo so I just use that. Both Nivea and Right Guard BW can be used as shampoo as well.
