It's luck really. I always do the many times payment trick.
For example the bill is RM80, so I pay RM10 x 8 times, so got 8 times cashback chances.
You can do RM15 or RM20 x times as you like.
I do the same with my Astro bill.
After tested. I guess the chances really still down to luck.
RM10 payment, shake bonus ranges from 20 sen to RM1 (even RM1 is very very rare).
RM100 payment, shake bonus RM4, RM5.
So I guess or can conclude here that paying RM10 X 10 times and paying RM100 one shot. Average out, the shake bonus you will be getting will be the same.
