There’s a site called Giveaway of the Day that gives away free, one-day-only downloads of licensed commercial software that normally sells for $25. $40, $50, sometimes even more. The giveaways are not trial versions, but full, licensed, unlocked versions. If you’re into games, there’s also a Game Giveaway of the Day. If you have a list of sites that you check first thing every morning, this is a good one to add.
