Favor From Someone Going To Grand Rapids

I wonder if someone could do me a favor on their way up to Grand Rapids.  I have a friend who's coming from the east coast who would like to try Gumballhead and Zombie Dust.  I'm currently out of town flying directly into Grand Rapids later today, could someone pickup a six pack of each for me?  I'll pay ya back or can quick-pay you ahead of time if that's easier.  If you can, I'd appreciate it.  Thanks!
