There are two days left to pick up the latest MacHeist bundle. Why would a bunch of Windows snobs care? Even if you buy it just for Tales of Monkey Island, you are still saving $15: that's why.

Tales is well worth the purchase and anything supporting telltale is good with me
I guess supporting charity is okay too

Warning: may only come with Mac version. Although the name of the site kinda gives that away.
[edit] Actually, I stand corrected. It'll bag you The Full Telltale Games Service (complementary Windows version, DVD copy for shipping costs etc).

Awesome! Thanks Jimmy!
Update: I can confirm that this works - I have successfully redeemed my ToMI gift code on Telltale's website, and I can download both PC and Mac versions of the game.
Unfortunately we won't know for sure that I haven't been ripped off until I see my credit card statement...
Also, it's worth pointing out that only a pittance of this purchase will go towards supporting Telltale (probably less than $2). In my case, I wouldn't have bought ToMI otherwise, so I don't feel too terrible about that.
For anyone without a Mac, it's also possible to gift up to 2 of the applications to your crazy Mac-loving friends via email.
I suppose it's also possible for your friend to get the whole bundle and give you the gift code for ToMI... but maybe you're not allowed to do that. I don't know.
