Oh Graze is finally available in the US?
Sadly I just threw away the vouchers I got off them (to give away) at Christmas. Figured no-one was interested, and they're not very good as a gift as they require you to sign up with a credit card and cancel later if you don't want to stay subscribed.
I get two per week and eat half a box per day Mon-Thurs at work. (Friday we get bacon sammiches...) helps balance out being slightly less healthy the rest of the time!
It's a pretty good system, kind of exciting to see what's in the box each time. You can bin stuff you don't like so they don't send you it again, I did that to the olives and the things most closely resembling bird seed / floor sweepings
Another tempting one was a subscription to The Grown Up Chocolate Company, but far less healthy. At £22/month for 31 chocolates ("box of chocolates"-size ones) though I didn't bother. That's some expensive chocolate.
