Part of the hunt prize from Somnia, 10 lindens.
"Show your support and come shop at the Wear Gray market this year and help us support the American Brain Tumor Association. Every store has at least 2 items that are 100% of proceeds towards the fundraiser. There is also a sim wide hunt with hunt items costing you 10L and all proceeds from those will also go towards the charity. To locate the hunt items, look for a hunt sign in front of stores. Those hiding hunt items in their store will have a sign out front to make it easier for you."
