You don't save that much, especially after the cheap trial. If you know what you're doing, a run to the grocery store will actually be much cheaper. I think it's more for people who want a home-cooked meal but don't want to go shopping or find a recipe.
We were a great example: some family members gave us a Green Chef subscription while we were both home on parental leave and it was a great way to eat better while having very little free time / energy.
