[Brazilian]

Hi guys, nice to meet you! I am brazilian and a fan of C's. I would like to know how could i get a fanpack? (a post that you receive cards of the players, things about celtics... that kind of things... in my adress... teams of NFL and MJB do this)

I would like to know how to buy things of Celtics or how to receive something free about C's. Is there a site that i could buy cheap things?

Thank you!
