OTOH, I think that's pretty cheap seeing as my baseball fan friends buy $200 team logo jerseys that they only wear as a fashion statement and not out of any need for their activity. Yes, cycling jerseys are expensive but you can find some cheap deals on them. I've gotten jerseys for $30 before. You can't even find some nice t-shirts for that price anymore. Check for closeout sales (especially in the fall and winter) at your LBS.
Mark up makes up for a lot of it. I have coolmax/synethetic shirts with all types of geometry in the weave that I got for 20 bucks retail from some no name house brand. It's the same fabric with flat stitching but no fancy logos or anything.
