I wouldn't do it, myself. I did subscribe to an organic veg/fruit plan years ago when they first came out but shared it with a friend as they delivered way too much for the three of us to eat each week. You get whatever's available, which is sometimes a problem. Who eats 4 lbs of beets a week? Or 6 romaine lettuces? You get what they're growing each season and you still have to go shopping. So, we stopped after a year or so. I think it was called Small Potatoes or some such.
As for meats, I like to choose my own, not get what they decide. I like to look at what's available and get deals. I also like to buy organic and unless they had a certificate saying it was, I wouldn't trust them.
And I would certainly not go for their freezer! That was a red flag to me. I try to clean out my freezer of meats regularly, and I do date the packages.
Mostly I have things like butter, pastry dough, soup stock, berries, peas, home cooked meat and fruit pies in there - they seem to last forever. I think Osso has something about protein items breaking down or whatever, unless they're cooked.
I bet you don't take them up on it.
