Randy's Free donut for bday pro-tip
I was looking to order my free birthday donut from the Randy's app. On the plus side I noticed it seems to let you order any donut for free, even the most expensive Texas (large) donut.
OTOH, I was going to order cheaper donuts too and pay full price. However, the app was going to apply the freebie to the cheapest donut. So I will just be getting the one free large donut. They're missing out on what could be a larger order.
