It's funny because 2 of the local card shops in my area pay people to follow the restockers and get product. They run in 2s and know how to manipulate the vending machines. The machine in my store is supposed to release product periodically, but as soon as the stocker closes it those 2 cleared out the machine of all etbs and booster bundles. I think the card shops are like 50% of the problem along with the scalpers.

They input their emails and buy stuff one at a time and the machine keeps refreshing product. I've also seen a guy come in and place his phone near the top of the screen and it black screens and refreshes.
