NETS held a Lucky Draw from June to August 2017.  Topup $20 x 2 times per month and get a chance to win $10.  That was practically free money from NETS every month for 3 months.

There were a few guys who won between 40 to 60 plus cards they used to topup every month, that's $400 to $600 plus free money.  Chances to win the lucky draw was extremely good don't u think so?

I won for the 20 plus cards I have (most gotten free), almost 80% win.  That's $200 of free money every month for 3 months.
