Bingo Card Creator is still plugging along, though both down from previous years and an increasingly small portion of my business. I spend under 20 minutes a month on it on about 2 to 5 issues which make it past T1 support.
Probably been addressed already elsewhere, but for a relatively static non-tech-dependent product, did you ever figure out why these were such epic months?
Can you tell me what browser/etc you are using? I replaced the cert a month ago on expiry and believe it is serving the correct one, and have verified this independently as of a minute ago, so I am wondering if there isn't a caching issue somewhere.
It was Google Chrome (36.0.1985.125 build 283153).
I've checked again today, and now I don't get a SSL warning. I am pretty sure I've never visited your site before, so I don't think it's caching on my end.
As for numbers: http://www.bingocardcreator.com/stats/sales-by-month Historically, multiplying by 60% usually gets a good approximation for profits.
