Graze looks like it's one of the best boxes out there. It's only $5, so like, YES PLZ, and every box is filled with delicious, healthy snacks. Sadly, you need an invitation code to sign up right now, but if you stalk your friends who were lucky enough to sign up for Graze and receive an invite code, then you might be able to get your hands on one.
Love With Food
The Love With Food box is also pretty cheap, and it's fancy gourmet samples, which is totes fun to get in the mail. It's a great way to try that $20 tea you've had your eye on without actually spending $20 on tea.

At $19.95 a month, the Vegan Cuts box is a little bit pricier than the previous two, but it's full of great vegan snacks. Since vegan products aren't found everywhere, it's a good way to try some stuff that may not be available locally. Plus, if you share this box with a pal, it's only $10 a month!
Cheating with this one a little because Bespoke Post isn't all food, but the food it does have looks b o m b. The Bespoke Post box is actually curated for men, but it's not filled with Axe Body Spray; the boxes revolve around booze, food and accessories, so they're something that people of both genders would be interested in. At $45 it's the most expensive listed, but the boxes, filled with coffee grinders and weekender bags, definitely seem worth it.
