I have some more info and updates for this.

-- Some of my customers who went to the dominos place to pick up the pizza had to pay $1 fee
-- Customers who had the pizza delivered to their house had to pay $3 fee.

A medium 2 topping pizza costs $11.49, therefor, I will decrease my prices to $3 per 60 points, $6 per 120 points and so on.
