If you search “bingo card creator”, I’m now result #8 through my download link at Payloadz, one of the folks I’m using as a payment processor.  Whee.  Its not that useful to me, though, because the web store design is not so hot.  I’ll have to get work on optimizing that.  Unfortunately, there is a limit to what I can do, and they link back to my main site in a way that is Google friendly.
