Get large 7-eleven Coffee for just $1 instead of $2.
How to get it:
1) Insert your debit card into the 7-eleven ATM
2) Type a wrong PIN
3) ATM will ask whether you like to get a voucher of $1 for the large coffee normally $2
4) Press/tape yes
5) Complete the ATM steps ( debit card account type, how much money to withdraw etc)
6) Transaction will be cancelled as you type wrong PIN but ATM will also generate a printed Voucher for you
7) Make your large coffee and show the voucher to the service attendant and you are good to go
8) Happy bargain
So this works 3 times until your card gets eaten by the machine?
