If u guys thinking like me, could save some bucks buying milk powder on the 28th of each month, u need to think twice.

My experience so far.
1. Aug 28, (sunday evening) - yes to 5% AEON BiG Thank You Day, 0 from visa paywave - acceptable, the pool for visa wave must have ran out on evening
2. Sep 28, before 12pm) - no to 5% AEON BiG Thank You Day, called service desk - the lady said the pool must have ran out. 0 from pay wave too

Gosh, the cash pool runs out before 12pm?
