My DIL shops at Rite Aid every week! They end up paying HER!
Between the coupons, sales, and rebates and whatever else she has signed up for on their web site... She even has a blog that she updates with what she bought and how little she paid!
She buys things that will give her a profit or close to it whether she uses the item or not! She then donates all the items to nearby woman's shelters!
