There are just four days left to enter our back to school sweepstakes with nearly $50,000 in prizes!

During the month of August, we published 14 back to school guides, covering product categories ranging from cameras and printers, to smartphones and ultraportables. With each post, we offered a selection of gadget must-haves, but we also gave you an opportunity to enter our massive back to school giveaway, including 15 identical bags stuffed to the brim (and far beyond) with some of the hottest devices of the season. You want these gadgets, and we want to help! The contest runs through noon (ET) on Friday, September 7th, so there's still plenty of time to enter -- simply leave a comment at each of our category pages, along with the giveaway post, to secure 15 chances to win. And to make things even easier, we're including links to all of our posts just below. Good luck, and have a fantastic semester!

Note: You may enter our back to school contest on the giveaway page, and at each of the category pages listed above as well. Comments left on this page will not be considered, however.
