Do you think I should get an A.P. jersey?

I am about to get paid a hundred and some dollars. I want to know if you guys think it would be smart to "invest" in an Adrian Peterson jersey? I'm a Vikings fan of course. Harvin is my favorite player, but I don't know. He seems like a player we may trade off for missing too many games :( Do you think A.P. will plan on switching teams any time soon? Do you think premier jerseys are worth the hundred bucks? Thanks!
