Thanks for your interest in the half price sale
I often go years between putting Chess Openings Wizard Professional on sale. I’m doing this sale to get more player designing their openings before the mobile versions of COW are released.
This sale will be private. There will be no web page that mentions it. I’ll email you – and if you buy the Professional version for Macintosh or Windows (normally $197) during the 48 hour sale it’ll show up as $98.
