If you want to get a jersey or hat or anything else of your favorite team... Sports Fanz in Teays Valley is the place to go.
I have been a huge WVU fan since I was a kid. I lived in Cincinnati and now Phoenix and every time I order something it comes quickly, and in perfect condition.
They have such a large variety of collectible/autographed items to choose from that makes it easy to find something for about anyone.
I went in looking for a special edition WVU football golf polo (which I got) and found other types of Mountaineer gear and accessories that I never would have known existed or needed (I walked out with a Yoda/Mountaineer decal). Put this place at the top of your list when it comes to WVU merchandise.
