I have been itching to play some old school Warcraft does anyone know where I may PURCHASE Warcraft 1 and 2 and possibly 3 (did 3 have a single player experience or was it all online)?

Warcraft 3 has a campaign, it's not all online. Quite a good one really. RIP Warcraft franchise.

Warcraft 3 will probably be the easiest to find, and yes it does have a single player campaign. Warcraft 1 and 2 you may have to look on ebay or amazon for.
