We are still not entering stores, so it's easy to list what we're missing from TJs, which for my money does very well by foodie home cooks:
Cheap salt crystal and pepper grinders
Pre-cut butternut squash for instant Ottolenghi preps
the aforementioned toasted pine nuts
inexpensive walnut halves & pieces
generous fresh herb packages and whole herb plants
packaged non-button mushroom varieties without rusting/spotting/mold (Amazon/WF can't get this right for delivery)
red peppers for under $4 per pepper
bulk citrus
Endive and radicchio assortment
canned dolmades and tuna
canned beans
$1+ marinated olive pouches with citrus
frozen chocolate croissants
full fat yogurt, sour cream, creme fraiche, buttermilk in smaller containers
small form factor / price balsamic and oils (avocado, sesame, olive, truffle)
absurdly low-priced cooking vermouth, bourbon, sherry, vodka for sauces and pies
soyrizo and tofu stockup under $2 per package
corn chips, popped dill popcorn, kettle chips
dark chocolate
hand and dish soap
small natural sponges
We've always done better elsewhere on proteins (especially fresh and frozen seafood), breads, fruit, cheeses and deli, name brand beverages and condiments, and most non-nut baking supplies, but for pantry stockup and some more durable vegetables, herbs, soy products and citrus I think TJ was regularly a 40% savings for us every other week for the same needs.
I don't at all get the unhealthy stuff comment when every Jewel, Mariano's, and Pete's is loaded with HFCS, artificial sweeteners, palm oil, and trans fats and most (admittedly abundant) TJ snacks eschew them. I doubt any foodie chef is using one store or source for everything, so in the balance of picking and choosing I'm missing them at the moment (and / but am not yet moved to send a personal shopper there for us).
