Recently in another thread (one of the money saving ones) there was some discussion about shopping clubs and in particular online shopping w/shipping costs... then today I saw this in my news reader: [saving on groceries] http://money.cnn.com/2008/06/13/pf/savings_groceries/index.htm?section=money_pf what shopping clubs do you belong to and how do you get the most out of them? we have been members of costco/costco.com for a while and it is worth it, but I feel like it's often hit or miss with what the physical stores have for selection. Certain things I know they'll always have but the rest, The article mentions Amazon grocery and my husband also mentioned Amazon Prime the other day... and it sounded interesting. Anyone tried it? I also place orders through Office Depot and over a certain $ amt it is free delivery, even if it's not all one shipment. They carry more thank just office stuff; so far it's worked out pretty good for house stuff too!
