I buy Gardenia Bread which actual cost is RM 2.10 but you can get RM 1.80 at the Medicine Shop at Sg Long and Mahkota Cheras.
So each week, I save RM 0.30.
One month, I save RM 1.20.
One year, I save RM 14.40.
I like to buy cheap thing. This is the website that will highlight some of the ware house sale:
