My son who is seven has really gotten into legos. He loves the mini figures. He now would like to collect the ninja ninjago minifigs. I looked on ebay and to my surprise 4 regular ninjas go for over $40.00. So these figures which are no bigger than an inch are getting over ten dollars. Its not like they are new sculpts. So why are mini ffigures so exp.ensive and popular? I like my superheroes figures,but at least i understand shortpacked figures go for more than standard general figures. I must say when i find a sealed mini ffigure,i will know my son will enjoy the figure with his legoes. Avian thank you for chiming in with your lego thoughts. : )
