The problem is this system works for ang mohs cos they dun have so many supermarkets/shops all over. Usually, they drive to supermarket and bulk buy. So on the way back, they can return the bottles. Also, these companies are eager to make a mark in Asia so of course they promote their RVMs very well and work closely.
SG refund system also ****** up. Use two refund method that majority of people may not use. I don't even use ez-link at all. Paylah that day was down exactly when I wanted to return. Nowadays all the bank systems seem to be down pretty often, quite unreliable.
