Has anyone had luck with these? We used to belong to one a few years ago, but stopped going. We could only eat so much corn flakes at a time, and some prices were really not better than hitting sales or clipping coupons at the regular grocery store. We also would end up spending $200 easily on just a few items, and STILL end up at the grocery store. We also would buy more impulse items, assuming they were bargains, but this was not always the case. If you have to drive more than 15 minutes to get there, is it worth it? If you pay an annual fee, do you really make up for it and more, in savings? Any advice would be appreciated. TIA!
