I go there several times a week- but only for the few items I like. We've compared TJ with others, but we're all really picky in my family- we prefer name brand spaghetti sauce, noodles, bread, salsa, chili, popcorn, crackers, yogurt, mac&cheese, etc. so I have to go to Safeway for those. Besides- hamburger, tri-tip, pot roast and such are always cheaper when on sale at SW.
The things I only buy at TJ's are: Butter (the best!), black forest ham, sliced deli cheeses, french bread, spicy hummus (Mmmmm), 2buck chuck, TJ beer, coffee, fruit, vegies, and frozen wild blueberries. (Actually, I'm eating a Black bean& cheese burrito this very minute!!)
