I have a 10 lb sack of potatoes in my veggie bin right now that I bought at TJ's. I get all my "staples" there. Milk, Coffee, cereal, rice, beans, olives (we eat a lot of olives in this house) bananas, yogurt, Olive oil, eggs, bread, grapes, organic spinach leaves (I use spinach leaves for salad almost nightly) Cheese. Mayo, Ketchup, broth, mustard, salad dressing, cookies. Pasta, chips, wine, salsa and hummus, spices and pancake mix. Cereal bars and crackers. Maple Syrup, peanut butter and fruit spread.
Things I get occasionally:
-Apples (they have great prices on organic, but they aren't always as good as the farmers market. I live in So Cal and have two farmers markets near me that provide locally grown organic produce, so I can afford to be picky about my fruit. If I lived in another part of the country I wouldn't have this luxury
-Oranges,these tend to come in a large bag and if I'm not sure my family will finish them I skip it.
-Onions, again come in a bag of 4, and we don't eat a lot of onions, I'm better off getting one at a time at the farmers market.
Bell pepper, tend to be four to a package, I have a heard time finishing just two in a week.
-Cold cuts for sandwiches, they have nitrate free there, and non-nitrate free packaged cold cuts. My family likes the flavor of fresh sliced at the deli better though, so I only buy at TJ's if I'm not going to be able to make it to the deli.
-Frozen foods, I get there flash frozen fish, Ahi or Salmon, and it's pretty good. Not as good as from the fish market, but I hardly ever make it to the fish market. I also by the bulk bags of frozen chix breast there, and some easy stuff for last minute dinners. Oh and their organic toaster waffles are my son s new favorite breakfast.
-Beer, my DP usually goes for a basic MGD, but once in a while he'll be in the mood to try something new, they have a lot of different beers there.
A lot of what I buy is organic, but not all of it. The coffee and chocolate are fair trade. I have purchased flour and sugar there before, but if I'm doing something like baking a ton of stuff for the holidays I am better off going to Smart and Final and buying in bulk, with a coupon for a major brand. The reason I buy everything listed above at TJ's is simply because it is much less expensive than the Ralph's (Kroger) market just blocks from my house. In some cases the same exact brand is double at Ralph's. If it weren't for Trader Joe's being two miles from my house I probably wouldn't even need a car.
eta: The other reason I have for shopping at TJ's is they have a great reputation for how they treat their employees, fair wages, insurance, even for part time workers etc. And also the way they work with their vendors. They seek out fair trade products and made in the USA products where they can. All of which I feel better about supporting, rather than larger stores who put profits before people in most cases.
