Whenever I get a chance, I also like to check out The Stadium Shop, nearby in Gateway One Plaza. They usually carry some interesting and unique Devils stuff. And their player T's are priced cheaper than at the Devils Den.
Plus, I'm sure they could use the business, thanks to the lockout.
Got a red Clarkson devils player tee from there last year. $20. Not sure it was authentic Reebok gear but it looked pretty close. Only saying that because the numbers and letters faded faster than the Kovalchuk one I got from Modells. But all in all I'd buy another there esp since they seem to have more player options for cheaper.
