I know that Walgreens and Rite Aid have similar programs but I am a huge CVS fan and prefer their Extra Care Bucks! You don't have to worry about rebates or anythign like that... you just have to clip coupons for just about every toiletry our household item you can find (because you never know what you'll get free) and you have to remember ot use your Extra Care Bucks before they expire.
So, how much do I save? Well, I have enough toothpaste, toothbrushes, shampoo, deoderant, razors, shower gel, medicine, etc. to last a year and got most of it for FREE.
It's kind of a pain at times. You have to keep up with it. I go in spurts... .like right now I am well stocked up (on the items listed above) so I haven't been messing with it too much. But being due (baby) in JAnuary, probably around the holiday time I will pick it up again and restock my supply.
God bless,
Julie
