Amazon has a killer deal on Lightroom 3 as its “Gold Box Deal of the Day” for only $119.99 – the cheapest I’ve ever seen the full version. Here’s the link.
Note that these deals typically don’t last all day since Amazon only has a limited number at the “Deal of the Day” price.
UPDATE: Looks like Amazon is putting up another seller’s offering now at $199; however, you can still get the Lightroom 3 deal by clicking the “Add to Cart” button for the Amazon product where it says “More Buying Choices.” It says “ships in 2-4 weeks,” but you’re still saving over $80 off the next lowest price.
