Basically as the title says. A local gas station chain has released a new app. They give you a one time $10 off your purchase of any purchase over $10 promo coupon.
The only unique identifiers for your account are an email and your number from a different loyalty points service. I noticed they don’t verify the loyalty points number so you can put any random number in as long as it’s the right length.
The $10 off only requires a $10 purchase. So if I spun up 3 accounts and went to 3 of their gas stations, pumping $11 worth of gas I would get $33 worth of gas for $3. Furthermore, it looks like this promotion works for anything in store, groceries or even gift cards. The only restrictions printed on the promo itself are tobacco, alcohol and lottery.
Their terms of service doesn’t specially state anything about having multiple accounts.
Is there anything actually illegal here or is this a loophole they didn’t consider?
Edit
After comparing two coupons back to back I just realized it’s the same barcode each time. I don’t even need to generate new ones.
That’s the MAC address isn’t it? It’s possible to use a random MAC address but apparently that only works with random MAC enabled WiFi networks.
On a PC it can be a number of things from MAC to various hardware IDs, but on a phone it’s a UUID assigned by the phone maker (different function calls for Android and iPhone).
