I have seen the socks in the pack as well, Randy. Matchup very nicely with the color stories for Spring 2012. I do not believe they are offered individually but your best bet may be a retailer/pro shop to buy those in bulk to sell per color. Could be wrong there.
What colors do you not like as much? I'm sure the ocean blue one could fit to your wardrobe if the Tar Heel moniker rings true. They look good with MyJoys, too!
