Y'all have 30 minutes before we stop considering submissions for our Charity Case contest. Here's what you have to do: Go to this post and, in the comments, guess the total dollar amount of the priced merchandise appearing in the September issues of the following ladymags: Cosmopolitan, Vogue, Harper's Bazaar, Elle, W, Marie Claire, Allure, Teen Vogue, Lucky & Glamour. The winner who comes closest to the actual number will have $200 donated to the charity of her or his choice. (The winner will be announced on Friday.)
