I was at the WF on Green Bay about a month ago, to get some tarragon for a dish I was making. I went to the bulk spice section, and they did not have tarragon in bulk. Spice House was closed for the day, and so that was not an option. I ended up going to the downtown Evanston WF the next morning, where I was able to purchase my tarragon. I really liked the Green Bay store when it opened up, but it is more geared to people that live on already prepared food, and don't cook. It seems like all of the WF stores have downsized their bulk department. I used to be able to buy wheat germ in bulk and they don't offer that anymore. I wish they had bread yeast in bulk like Oak Street Market used to years ago, but they don't, because nobody makes their own bread There has never been a one stop shop for me. In the past week I have been to WF, Jewel and the farmer's market, and the great majority of my money was spent at the farmer's market.
I am not a big fan of Trader Joe's, and only go there 2-3 times a year. I was there several weeks ago to purchase their Greek olive oil though. That is one of the few things I buy there, and they were crazy busy, and most people were buying way more than I was. I think the store appeals more to people that don't cook much who mostly buy their already prepared stuff.
