instead of the $249 pricetag, until recently it was only $89 in Melb, so I am not sure why the price is different.

I'd say it's because some people seem to think if they are the only ones to have one they need to stick it to you if you need it.  Then when they get competition they tuck tail, run and make up stupid excuses why they all of a sudden need to drop the price or they bait you into buying using some BS like "last ones" available when they're sitting on a couple dozen.  Funny stuff...unless you're the bloke in need.  You never see that kind of behavior at RTBB and the other vendors who are honest and have integrity.

As for the windows, they are currently being worked on here in the states and once finished you won't see anymore $200+ pricing ever again.
