I first heard about Trader Joe's when they were only in Southern California. I lived in the Bay Area at the time, and when we had visitors from LA, they would invariably bring nuts or other goodies from TJ's.
Fast forward a dozen years or so, and Trader Joe's had spread all the way to Washington State! Much happiness in Whoville. :-)
I go there at least once a week to buy everything from spaghetti sauce to fruit bars to Cheetos-clones (without all the additives and dyes!). Cory's latest must-have breakfast food is toaster waffles, so I stock up on a whole-wheat, dairy-free variety that's pretty healthy. And at TJ's, they're also inexpensive!
Love that place.
