This one's kinda $9.99, but essentially $14.99...
September's issue of Best Buy's @GAMER magazine has a coupon in it for $20 off the console versions of Brink or Hunted, or $10 off the PC version.
Best Buy currently sells the console versions for $29.99 and the PC version for $19.99. The magazine sells for $5.
($29.99 console game + $5 magazine ) - ($20 coupon) = $14.99.
($19.99 PC game + $5 magazine) - ($10 coupon) = $14.99.
This will be an in-store only offer, since these coupons can't be used online. The coupon's start date was Sunday, 8/28, and they don't expire until the end of September, so you'd have all month to take advantage of this deal.
