A friend recommended this site to me for basic necessity shopping. The site cashes online coupons in addition to keeping a running shopping list personalized by you. The bonus: the items are delivered to your door at no additional cost. You can set up a schedule of products to be delivered every 2 weeks, or whatever your timeline allows. I’ve only played on the site, and not actually placed an order, but I have it on good authority that it might be a life changing experience.
