I've tried it. The food is decent. If you have a lot of money to throw around, I say go for it.
Otherwise, it's definitely cheaper to just spend a day cooking some meals and freezing them like homemade TV dinners for the upcoming week.
Overall, some of their items just really don't reheat that well. For example, the frozen french fries come out soggy when you microwave them. I ended up popping them into the oven to reheat them, but then I asked myself why I didn't bother just buying some veggie burgers and frozen fries at Trader Joe's for $10, which would be enough for 6 meals, instead of spending $8 on Gobble Green's 1-person veggie burger & french fry meal.
