I subscribed to the Taste Trunk gourmet box for awhile. Not cooking tools, but definately geared towards cooking rather than snacks. A lot of spices, sauces, dressings, etc. There's a "healthy chef" one too, but it looks like it's currently only available as a one-time box or a prepaid subscription, rather than monthly. Their website is kinda weird. I keep thinking about resubscribing. It's more expensive than I'd pay for any other subscription box, but I think I've enjoyed the stuff I got in it more than I have in other food-related boxes. I got somewhat behind on using the stuff, but that's probably partially because I get stuck in food habits. I got a pineapple salsa in one, and after I finished it I ended up making my own pineapple salsa for a while. Only just opened the bottle of mild indian curry ketchup a couple days ago. (It's good, but distinctly curry-ish and not really ketchup-ish. Nice with sweet potato fries.)
Anyways, how much use I get out of it seems to depend on how experimental I'm feeling, and I got to the point where I had a lot of things from the boxes still waiting to be used. I'll probably resubscribe after I've used up the backlog.
At one point they were doing a mini-trunk thing, but that doesn't seem to be offered anymore.
But anyway, if you're looking for things to be used for cooking, you should definately check that one out.
