Obviously you can save money if you buy everything you need in bulk. And if you are buying online you also get free shipping which will save you even more money. I've seen a few "shopping clubs" on the net. By cutting out retailers/middle men they get huge discounts. While sourcing products directly from manufacturers for a small club could be overreaching, even buying from retailers you can get some discounts on bulk purchases, which is good enough. Have any you ever thought of creating such a club? You could ask your neighbors and friends to join.
