If you send in four wrappers, $3.99 for shipping and handling, plus your address you can get a free autographed card. They say to allow 4-6 weeks for delivery but I received my card in about two weeks.
Overall, I'm pretty happy with what I got. I wasn't expecting a Jason Heyward rookie but getting an autograph from a fairly recent product is nice.
2008 TriStar Projections #308 Francisco Castillo Auto
Francisco was with the Yankees organization through 2008 and then played Independent league baseball in 2009. I can't find any stats for 2010 so it might be all she wrote for his playing career.
