Only one I know of is http://yukijersey.com and they're pretty darn good. The quality is great for the price. My only issue is there's no size chart so it's a gamble if you get the right size or not.

A friend of a friend has ordered from them. If you buy ten jerseys at one time, you get free shipping.
I signed up for their mailing list and they sent a 5% off code. It's a one time use code though.
the jersey's are pretty much official at a fraction of the price since they are sold by the Chinese facilities that make them for Nike. The shipping is high but its the same price regardless of how many you get so awesome for group buys.
