Riddle Me This - Arcane Vault Version

I love how Arcane Vault are always coming up with fun new contests and things. It's awesome how enthusiastic they are about Vampire Academy and listening to the fans! :-)

Just in time for Halloween, Arcane Vault has posted a riddle on their Facebook Page:

The best place get Vampire Academy Product + the total number of Vampire Academy Books (as of December) x 11 + half that = 20% off coupon code November 1st – November 7th.

I love these kind of things! Hmm, what can it be? When you figure out the answer, e-mail it to vaultkeeper@arcanevault.com. If you're correct, you will get an e-mail, and a coupon for 20% discount on the website.

The answer to the riddle will be given on Monday, and if you need a little hint as to what the answer might be, you can find a few here. (I didn't want to post it here in case you wanted to figure the riddle out without any clues. :-)
