Do you get a choice of what you get or is it a mixed bag box of stuff that is in season/available?
With Riverford, you don't get a choice, you just get what's in the box for that week (varies from week to week). Details are published each week on the website. Different size boxes have different selections: in other words they don't just differ in quantities, so if there's something you want to avoid, you can sometimes get around it by taking a different size box. Not really suitable for people who have allergies or strong aversions to stuff, but we're lucky in that respect. And this policy enables them to keep the costs and food miles down, I believe.
Just checked on the site, and the prices are going up next week. Bummer! Oh well, that's food inflation.....
I should have added that the packaging is minimal and a lot of it is re-cyclable. The sturdy outer box: they take that back the following week and re-use. Things like tomatoes and mushrooms come in cardboard punnets which will go in the recycling bin. Some items come in polythene bags - not sure about biodegradability but they get some re-use for binning rubbish.
