I see what people mean, by categories vs specific stores.
I will keep for now my store specifics, as I'd like to know how much I spend at them, but I realize especially for Costco and Sam that what I consider groceries is often bought there so the exactness of the tracking is pretty fuzzy since I won't be itemizing each thing in a receipt. If its mostly groceries, I'll just put it in groceries.
I realize I'm making this harder on myself than it would have to be, but I won't use anything to directly access my spending information (like CC accounts or banks).
One habit I find I have to change is where I empty out my wallet, if I do it at the computer, its easy to enter the receipts, but not if the wallet is in the kitchen
As a quicken user I have Costco default to groceries (I can change it if I bought, say, a big tv). I also have Vons and Sprouts default to groceries... So under "groceries" - I can tally how much I spent at each store.
Same with gas - there's a discount place near my house, United Oil... it defaults to auto: fuel.... so does Costco Gas (which pulls in from creditcard as costco gas, not just costco).
Then - if I wanted to see how much I spent at costco overall - gas, groceries, optical, etc.. I could search quicken for all transactions with Costco....
But really - all I care about is am I overspending, is it something I need to change.
