Leopard on new Macs?

Hi,
Well, this is a bit of an unusual question. I want to buy a new MacBook after over 10 years on PC, but I understand Leopard is coming out on October, so I'm thinking of waiting until it comes out, to get a Mac with Leopard already installed.
I've tried to check if buying a Mac now (or anytime between now and October) will grant me a free or cheap upgrade to Leopard, since it's so close to the release date, but my local distributor (Israel) doesn't know and I searched, hopelessly, for a way to send a question to Apple - Their site has everything except for a contact form!
Does anyone know how can I contact Apple directly, or what is the usual policy concerning upgrading with a new computer? Oh, and are there any rumors about the exact release date for Leopard (I mean, is it early or late October?)

I can't wait to get my hand on a MacBook...

Thanks,
