Italian wine recs <$100

[Merlinesque]

Hi!

Some friends of mine who were recently married are really into wine, especially Italian. Since I'm not a wine drinker myself but would like to get them a bottle of something special, I'm opening my request to this board:

(1) For @$100 (U.S.), what recommendations would you make for a fine bottle of Italian wine?

(2) Given said recommendation, where on the Web would you suggest I find, purchase, and have sent as a gift to my friends this wonderful bottle of wine?

Thanks so much for your time and have fun with your ideas.
