A toy time capsule. Also, a place for regret - the regret of not having kept your toys in their packaging and seeing their worth increase over time.
Nonetheless, Toy Shack does offer you a jog down memory lane; of a time where you had no worries, just your toys and imagination to keep you happy.
However, shelling upwards of $30 for a toy that brought you happiness as a youth will not make you happy. Keep your money, memories are priceless.
