Kent, which Schreiners are you referring to? Schreiners Gardens specializes in iris - to my knowledge they don't sell anything but - and that's the only Schreiners that comes up on a Google search for mail order nurseries. Bearded iris are certainly not lilies and not even exactly bulbs (although they are rhizomatous), so I'm not sure what kind of comparison you are trying to make. New introductions of bearded iris can be very pricey, as can new introductions of various plants, including daylilies.
