CS3 Design Standard is $150 at my school bookstore (academic version obviously). I got the Premium for $300. You might want to check local universities for their prices.
Yeah but you have to be a student (and prove it) to get those prices. The way the OP phrased his question sounds like he is looking for a regular version.
I have been looking to upgrade (non academic prices) from 2 to 3.
When I bought CS2 I used a company that buys in bulk (or thats what they said) to get the prices down a bit. It was viosoftware or something like that out of Colorado. They were legit and had a decent price.
I'd be careful about "too good to be true" deals.
Its looks like $899.99 to $1,200.00 (US) for CS3 Standard Mac is average.
Wow, its seems as thought the windoze version consistently sells for less?????!
hmmmmm, why?
