Realising we never got to the Farmers' Markets anymore, but were fed up of supermarket veg, we tried the introductory offer (a half price small veg box) and liked what we found. We now get a box regularly from Ten Mile Menu.
The system is really flexible - you can set up a regular order (weekly, fortnightly, every four weeks) or pick and choose each week as you go. Whatever is in your basket at midnight on Tuesday is what they'll deliver at the end of the week. You register payment details once at the beginning, and after that you are automatically charged. We have once ordered something that was unavailable, and they emailed to let us know. We find the different sizes of veg box offer a good range of options - they tell you what will be in each one and how many people you might expect to feed for how many meals.
The veg and meat are extremely good quality - the lamb chops are probably our favourite so far, but the beef mince was also good. If you've been shopping in supermarkets for a while it's easy to forget how flavourful good food is. It's a relief to eat carrots that taste of carrots! And there's much less packaging too. The veg boxes are returnable, and there is SO much less plastic.
You can also specify one thing you can't stand, and they'll replace it with something else. We are stretching our imaginations and recipe books (anyone have a good recipe for kohlrabi? Jane Grigson is very grudging about it...) but that is part of the fun. We're definitely eating better, more seasonably, and more varied. If it all got too oppressive and the veg box was dictating what we had to eat we could easily take a break for a week. But for now, it's like getting a present every week!
