I feel the need to write a review to contest a lot of the "free box isn't free" reviews. For me it was very clear what you were doing when you entered your credit card info, and I personally think it's pretty reasonable that you should be expected to enter a credit card for this. They were very up front about what entering your cc info meant. I had no issues with being charged unexpectedly, no issues at all with unsubscribing, although if I recall correctly the link to do so was a little bit hard to find. I do not know if user error factors into any of the problems a lot of other reviewers had getting charged/cancelling but my experience was super easy and without problems. I think it's reaching REALLY far to call this a scam.
BUT in terms of the product, ironically enough I didn't like it and cancelled my subscription after I got the second box. It's too expensive for how little you get (SO expensive!), I don't feel like you can customize the stuff you get very well at all, the snacks were repetitive and, to be honest, not very good. I got three boxes that were basically nuts and seeds and dried fruits rattling around in a 1 oz box with slightly different flavors. Not worth it.
But the company itself I had no issues at all with. Take that however you want.
