How to buy Sugar Cane with Only 45 cent!!

Guys,

Not sure if you guys noticed or not, we can buy sugar cane at only 45 sen in CareFour, Alamanda.
This what I have done..

1. Went to Alamanda to register my Maxis postpaid plan.
2. Bought Sugar Cane RM1.45 at CareFour
   
3. Get free stamp parking at service counter(worth RM1 below 2 hours)
   
4. Total I spend RM1.45 ONLY instead of (RM1.45 + RM1 Parking = RM2.45)
   
5. So, my SugarCane is only 45 cent

Hahaha..Can I count like that??
