I, personally, have no issue with WM, but it seems as though your experience and beliefs have led you to make a decision, which is great! I believe you can find, along with using coupons and shopping sales, equivalent prices at grocery stores, drug stores and dollar stores.
A good friend just told me about http://www.couponmom.com. It is a FREE "grocery game" style website. You match coupons to store sales to get good prices on the things you need. It may work on a stock-piling system (meaning you buy a lot of certain things now and use them over time so you aren't buying that item as frequently). I haven't actually explored the site, but my friend seemed impressed - she's more into grocery gaming than I am. But, it might be worth checking out!
