Casual-wear brand BSX is holding a "Big Bang 99 Secrets Hunter" advertising campaign with their models Big Bang. This new headlining marketing method is going to be a on and offline treasure hunt. Big Bang's me2DAY will reveal hints about where the treasures are hidden. Every Wednesday, there will be an online mission. Every Saturday, there will be an offline mission. There are 99 secret boxes to find and in the box, there is a signed item by Big Bang, a coupon for BSX and more. You can find out about more information on BSX's blog. It seems pretty fun. [gallery]
