If you haven’t checked out NatureBox yet, here’s another limited-time deal to entice you: Through June 30th, 2014, you can visit this page and opt to receive 3 delicious full-size snack options from them for just $5 delivered.
(Ordinarily you pay $20/month for 5 snacks, so this is a nice bargain.)
To get the deal you do have to sign up for a subscription, but there are no rules about maintaining it. If, for some reason, you decide you don’t want to continue on at the regular price, you can cancel without penalty. I think you might decide to stay with them, though, because their snacks are amazing and delicious and there’s no yucky stuff in the ingredients.
