My wife and I shop at both Costco and TJs. They are our favorite stores...

We're a bit odd though. Highly budget conscious, 4 kidsto feed (including 2 teenagers), and European tastes in food.

I don't think this is abnormal. I think every family in my (middle class+) neighborhood does both Costco and Trader Joes. We don't have a convenient Whole Foods though.
