I can't really speak about Costcos vs. sam's club, but one year i did very careful price checking compared to my other alternatives in my area, including 2 area supermarkets (stop n shop and Big Y) and a discount supermarket (Xpect Discounts).

I found that Costco had moderate to great savings on certain items, but not so on everything! It's not good to assume that if they offer a good price on Classico pasta sauce that everything will be priced accordingly. As usualy, it's a time consuming task to figure out where the best buys are, particularly for your higher expense or more frequently used items. I try to be as up to date on specific prices as i can, tho no longer have time to maintain a "price book."
