I was up by my old LYS today. They used to carry cross stitch patterns and supplies, but they stopped a few years ago. I saw a sign in the window that said they had cross stitch stuff, so I figured they'd started again, parked and went in. Sadly... no. They still carry needlepoint, knitting patterns, and yarn (so... much... yarn...) but no cross stitch.

I could have picked up some really nice yarns, but I'm on a self-imposed yarn diet. My stash is so big that one of the bedrooms in my house is known as the "yarn room".
Michael's carries cross stitch supplies, including kits, patterns, DMC floss, aida cloth, and embroidery hoops. HC, if there's a Michael's near you, check there. Unfortunately, they have yet to emerge into the 21st century - they do have a web site, but you cannot order online.
