Currently there is no option for customers to add individual meals to a plan (say, ordering a 6-meal plan but adding 2 meals to get 8 meals total). Our packaging is temperature-tested extensively and designed very specifically to hold the set amount of meals for each plan. That's how we can be so sure that the meals will reach you securely and also allows us to limit packaging waste. You can, however, have two subscriptions active at the same time to receive a number of meals different from the 4, 6, 9, and 12 norm. As an example, you could order a 6-meal subscription and a 9-meal subscription and get 15 meals a week or perhaps order a 4-meal plan and a 12-meal plan to get 16 meals, per week!
