non-Mother's day cards? how about non-Father's day?

[http://dummy.us.eu.org/robert (robert)]

This may be a frequently asked question, but does anyone know of any
companies that sell nonMother's day cards or nonFather's day cards?  As
usual, again, this year I bought Hallmark cards and modified them a bit
for those females in my life that are childless.

Thanks.
