Once you sign up it's very hard to make changes in time for your next delivery. They don't send a reminder email that you need to do this within a time frame to ensure you don't get foods you don't want! I think that's their big mistake and I will not be using them any further.
Tip for consumers: For many time stretched people these meals can be very useful. They are costly though for what you get. There are options to upgrade your choices to premium but come out very expensive. Be warned!!!
