I find some of my best deals in eBay: mostly random team jerseys of good quality that are overstocks. My latest purchase was a Giordana women's team jersey for $20 shipped I also purchased some matching bib shorts for $30 shipped!

I just checked my eBay profile and the seller isn't selling anything anymore =/

The only problem is that it's virtually impossible to predict when these chances will arise so you have to buy them when you find them...and be less picky about the colors
