I've been getting a box every 2 weeks from Graze for quite a few months now. I'm sure you've heard of it, but if you haven't then you basically get a box of 4 punnets - the foods are selected by how you've rated them on the website [goodbye olives, yuk!] - mostly healthy stuff. I say mostly, as there is the odd bit of chocolate and flapjack thrown in, although it's not so much that you'll feel bad for eating it!
This is the box I got today - excuse the rubbish photo, it was taken on my blackberry:
I got super berry detox, lemon meringue pie, orange & ginger flapjack and cherry tomato, basil and puglian pesto focaccia.
My favourites so far are probably super berry detox, chanachur panch phoron, honeycomb flapjack, copacabana and naked goodness seeds - yum! But there are quite a few I've yet to try as they've recently added new foods, all which look really good.
To get a free box use the code 6QL8WVH - you'll need to stop your boxes after if you don't wish to receive them anymore. You can also use the push back button to postpone them on a week by week basis. Oh, and they cost £3.49 [free delivery] normally!
