at the very least, you owe it to yourself to drop by and pick up one of these:
pinot grigio salami; 2.99 per salami = awesome and tasty, and freaking cheap.
they have a cab salami, but I've yet to try it. I'm newly addicted to these things...I almost started a thread here to worship the pinot grigio salami.
Also, if you like shitty cheap beer, then pick up some Simpler Times Lager. $2.99/6-pack. at 6.2%, it's way tastier than Budweiser, and will get you loaded much faster for half the cost!
Mission Street Brown is quite good, as well, for a $1.99 32 oz.
They have different beer selections depending on the market. They are the cheapest distributer for Mendocino Ales around here, which is an excellent thing. I could pick up Old Rasputin in the midwest for somewhat cheaper than elsewhere, but they don't carry it in CA, according to the supply dude at the TJ's down the street.
Trader Joe's specializes in decent to quality food for quite cheap. Most of the food is of the frozen-prepared variety though, but it is generally quite good.
