I don't know how to set this up yet, but I figured we needed a page that starts the ordering process. Here's my vision:
This page takes customers through the following sequence:
1. how many days do you want to "be served," 3, 4, or 5. Click through to next page.
2. It shows this week's combo, so if the customer picked 3, they'd see the 6 meals they'd be getting (lunches and dinners). There's a "stock your fridge" button, that clicks through to the next page.
3. Pay. We process the payment. Obviously we'd eventually want this to be automatic, but for now.
