Where to find bedding?

I'm going with "Gray with splashes of yellow" for our bedroom, and I'm looking for a bedding set to follow. I've already looked all over walmart, target, bb&b, jcpenny, macy's, and 2 other .com's but haven't found anything I like.

Do any of y'all know some websites I can check out?

I really like the set that mrsoconnell has on her farmhouse bed post. I'm not a huge fan of busy patterns, and like modern styles, but there's always exceptions for everything.

Thanks for your help!
