Normal Wii U deluxe is a bit hard to find but Zelda bundle has a lot of stock though.
RM1150 Zelda Bundle + 180 for 3D World + (3 x RM150) for 3 Wiimote+ = RM1780.
Quite expensive since you need 3 wiimote... but if you have older controllers it works too.
Super Mario 3D World works with a bunch of controllers. You can use various options like the GamePad, Classic Controller Pro, Wiimote/nunchuck setup and the Wii Classic Controller as well.

What on discounts? The console and others? Nintendo stuff hardly goes on discounts.
Games and everything rarely drop in price so does their official controllers and etc.
2nd hand games for some can become super expensive in a long run since they are out of prints and etc.
The only thing that did go down so far are the Wii U console which I think won't go down for at least another year.

Original ones are probably hard to find here.. Since most people pirate it..
Need to import from the US most of them. They are cheap as well now, most of them.
But popular titles might differ.. also rare ones that is out of print like Xenoblade.
