I think there is some confusion as to what he means by 'placing an order'. First of all, he's not ordering anything. At best he is loading these items into a shopping cart, who knows, maybe that's not even necessary depending on how the API is setup.
Second, it's not $18K worth of product are every location. He is almost certainly adding one value menu ice cream cone (or maybe chocolate sundae) from, one from each location. These cost between $1-$1.50 depending on location. A quick search says there are probably just shy of 14K location in the USA, and based on these assumptions, the ~$18K 'order' works based on these assumptions.
So, in essence he is filling the 'basket' with one ice cream cone, one at every location, and checking the results of which locations are willing to fulfill the order. I don't think this is malicious like some have imagined. It's silly, and fun, and I was happy to come across it today!
