I have a boxed copy of Lightoom v4 (full, not upgrade) - opened once to have look inside, but never installed. Windows and Mac versions are on the disc. Bought new from B&H.
Asking $50 shipped and PayPal'd in Canada/US.
Upgrade to v5 is $79 (from v4), so this is an easy way to save $29 if you don't already have a copy of Lightroom.
Thanks for looking.
