Hypermarket you must wait for the Sale period, sometimes they like to offer certain types of stuff at cheaper price. Maybe more expensive than standalone shops, but from experience the warranty claim process is easier, it seems that the manufacturers are more ready to help you if you buy from these hypermarkets.
Anyway, last year my dad bought a washing machine, Panasonic. The price after offer was cheaper than those standalone shops, and free delivery some more. The shop charges RM 30 for delivery.
