aiyo, you don't believe? i have been doing this for many years until some "smart" staffs started to refund the credit back to gift cards or credit cards instead of refunding cash. so i changed tactics to cash vouchers (reasons as i posted above). and this is how i always maximise my wise x2 and mbb2amex x2 beside other cc. whenever i have extra unuse cb i will buy cash vouchers.
ok, if really want to share all these hypermarket tricks/tips too many la. ok la, i share a few more to you all.
do you want to get 3x points at mydin for each rm?
1) buy cash voucher = 1 point
2) use cash voucher to reload tng = 1 point
3) use tng to buy stuffs = 1 point
do you know how to keep getting mydin points + keep extending your cash voucher at mydin?
1) buy rm500 cash voucher = 500 points
2) use the cash voucher to reload rm500 to tng = 500 points
3) use the rm500 in tng to buy again rm500 voucher = 500 points
4) keep repeating the above 2&3 for 500 points each time
5) by doing this also your cssh voucher is extended each time (so not only limited to 3 months only)
remarks: each time reload tng will charge 50 cents, but you still gain in long run
i don't believe someone has ever done this before. if someone trying to claim they did this before is surely a liar. so shall i now ask people to say i'm a genius and compliment me? lol...
anyway, after sharing these tricks i believe mydin will soon change their t&c... perhaps no more points for cash vouchers or no more points for tng reloads or cannot use cc/tng to buy cash vouchers... or all the above... but i will surely find the loopholes again. lol...
I believe easiest way for the hypermarket to 'block' this is just don't allow CC/TNG for cash voucher. But this will cause a lot of aunty/uncle complaints.
