Lame Linux

I was browsing MicroCenter yesterday, and looked at their Linux selection. Seems to me like they used to carry the majors, Red Hat, SuSE - I know I remember seeing SuSE there (pre-Novell). The only recognized brand I saw yesterday was Linspire, a few generic repackaged CD's, and a couple fairly obscure brands I don't remember. None of the majors were represented.

I wonder why this is. Is it just too easy to get them off the internet? Has the market for purchased editions collapsed? Did they get stuck with too many copies of older versions as distros evolved too rapidly over the last few years?

I checked the book section. Plenty of Red Hat books, only one on Ubuntu.
