Shaun buddy. Hey there!
The two places I have had the best luck are at GG for retail and then local green grass shops, like my local courses. I got some FJ stuff at The university of Michigan course last year as well, but I don't think you want UM gear if you live in Madison!
The other place with good inventory is TGW. I just bought a FJ ProDry polo a couple weeks ago. Only draw back there is no course logo on the shirt (I love course logos).
