Punching works but it depends a lot on a human factor, the cashier might decide to do it and might decide not, this method is more of an back up to you doing shopping for youre self, for example you wanna buy something and you try this method if the cashier doesnt do it then you just pay cash anyway, but basing a business on it as a means of income is gona be very hard because you will have to be running around from a store to store.
101 is not dead, its just hard to get good cards and some vendors are starting to price good 101 cards very high some charge as much as a 100 for a card, which in my opinion is insane. They just realize that demand is high and supply is short so they jack up the prices....
