RM550 is about $185. For what you get (materials, build quality, customisation) then I think the value is outstanding already. I think they may do occasional 10-20% off sales from time to time, but they are a small business.
I have actually handled a few in my time, and they truly are excellent. It's not exactly my style however. If you compare to Timbuk2's normal prices for example, it's about on-par but you are comparing a very good mass-market brand with an excellent artisan brand.
