There are several options available on their website, including different sizes and either all vegetables or a mix of fruit and vegetables. You can also add on groceries like bread, dairy, and other specialty items like this amazing maple pecan chocolate!
I tried the all vegetable box, which I ordered just a few days in advance, and it arrived in this green crate that can be left out for them to pick up the following week. There was a sheet taped to the side of the crate listing all of the ingredients, and their website featured several recipes using ingredients from that week's box.
I used the purple carrots to try this Moroccan Raw Carrot Slaw, which was quick and easy to make and tasted great!
I also used the tomatoes, basil, and and onion to make this bolognese sauce along with some sausage and ground veal I had in the freezer from my winter meat share (served over gluten free spaghetti)! 
A standard box is enough for 2-3 people for the week and costs $32; for the quality and convenience of having it delivered I think it's well worth it and would definitely order again.
