While you're choosing a Weekly Subscription plan, the page can show a running price per meal (your plan's subtotal divided by the number of days per week × meals per day × weeks) and the total number of meals per week the selected plan works out to, so you can compare plans without doing the math yourself. Both update live as you change plan options. This is controlled by the store's "Show Price per meal on subscription ordering summary" setting in Client Config; when it's off, neither number is shown.
