the appeal with trader joe's is the variety and the quality of their product, all at very competitive and very reasonable prices. i have no idea what $8 bottles of peanut butter dcm is talking about.
i second the 'have you ever been to trader joe's?' query. and you have totally got the book reversed on TJ/WF. was not long ago that people shopped at whole foods despite their exorbitantly expensive prices, just so they could say they shop at whole foods.
