Block Market

The meal block marketplace. Students sell the meals they will not use to students who want them.

Trade what you already paid for.

Most first-year university students are required to buy a meal plan. Semesters end with meals unused, and the money is gone.

Block Market lets a student sell a meal they will not use to a student who wants one, at a price the market sets. The seller recovers value from something they already own. The buyer eats for less than the dining hall charges.

We think students should be able to trade what they have already paid for.

How a trade works

  1. 1A buyer picks a spot on campus, orders what they want, and pays with Apple Pay or a card.
  2. 2Sellers with meals to spare see the order and what they will earn. One claims it.
  3. 3The seller places the specified order for pickup using their meal plan credit.
  4. 4The buyer picks it up.
  5. 5The seller gets paid.
