I noticed that, I threw it up because they usually disappear in 5-10 minutes. They just had an Evanescence signed that lasted maybe 2 minutes, silliness. Nice on the Ontario call too.
As noted before, this is just a St. Louis MO record shop that gets a signed copy or two for charity, of bands that come through and play a nearby venue, so they never have any deep stock of anything listed.
(similar to venues that have the artists sign their event posters and then sell them).
