Check out IceJerseys or CoolHockey...they typically have sales during the summer for deeply discounted or even free customization and they do hand-stitched. It isnt the iron on crap you'll find at the Devils Den.
Another option is just buying a blank from them and sending to ExclusivePro
CoolHockey is actually having 30% off all orders over $170 it looks like which gets the price down to $170
Best bet in most cases for the bolded scenario IMO is to buy the blank from SportsK. They usually have better prices on blanks than CoolHockey or IceJerseys. It also appears they have a standing $195 price on customized Adidas jerseys; right now Devils road jerseys in selected sizes are available. SportsK is similar in reputability as CoolHockey and IceJerseys IMO (have bought from all three, including a customized jersey from SportsK).
SportsK also has some good deals on retro/vintage (1982-1992 Devils and Colorado Rockies) jerseys, both blanks and selected player jerseys. (One minor negative if you are picky - in a couple cases, they are selling jerseys for players who never wore the jersey, i.e. Taylor Hall in a CCM vintage then-road (red/green) jersey.)
