My point of view is that paying full price you also save money.
Well, too be true, if I knew about one of those sale periods you talk about, I could wait, let's say, until next month, or so. I mean, saving 10% if I have to wait 2 months for my AX8 it's not a good deal.
The only thing I regret about my AX8 is not buying it 2 years earlier. That would have saved a lot of money (all the money I spent in other gear).
I'm just trying to cool it a little. Don't take me serious. Be patient, and when you finally get it, you'll probably regret for not buying it earlier. Or not.
