Expo specials! For the twelfth consecutive year, dealmac writers will be at the Macworld Conference & Expo in San Francisco for our exclusive coverage of all of the show specials worth sharing. (Even though Apple isn't attending.) Things kick off early Thursday afternoon (Pacific time) and we'll be posting new show specials as they become available. (That is, providing the weather doesn't delay our staff too much!) Check out the exhibitor list to see what companies will be in attendance; we'll also be listing deals from online merchants not at the expo. All show-only deals end February 13.
