Moosey,
Which Monkey Sports did you go to? I have had a few done at the store in Irvine. They cost $59.95 to do the jersey regardless if you buy it at the store or not. All the ones I took there were blanks that I bought some where else. The biggest thing to get is the "tackle twill" and name plate to make sure it likes the official one.
If you go to the Irvine one, ask for Jeremiah or a store manager. They will make sure you get it correct and at the correct price.
