Buy Lightroom 3 Recently? Get a Free Upgrade to Lightroom 4

Last month some retailers had short sales that heavily discounted Adobe Lightroom 3, selling it at $70 and $80. If you were one of the people who jumped on those deals, here’s some even better news for you: you might qualify for a free upgrade to the newly launched Lightroom 4! Adobe’s upgrade policy offers complimentary upgrades to people who purchase an old version shortly after a new one is announced, but it can also apply to you if you purchased shortly beforehand. Here are instructions on what you’ll need to do.
