This is NOT regarding personal "cleaning out the closet" sales posts! This is for "Torrid is having 50% off their clearance!" and "Just so ya'll know, here's a code to get 15% off at Igigi." These are GREAT pieces of information, and now they'll all be in one place.
EDIT: We cannot currently backdate community entries. We are trying to find a work-around for that. However, this post is linked to on the community info page and, by using Livejournal's Message Center, you can track comments to the post and be notified every time someone leaves a new code or discount. Just as if it were appearing on your friends list but without getting lost in the backlog!
