That's great, happy birthday. Try to find out what you did to get those 3 sales, then do that everyday.
With CB it's almost impossible to duplicate conversions. Sometimes I can go a week without a single sale and then some weeks it's a landrush of conversions. I gave up on trying to optimize for CB long ago but it is a good secondary source of monetization.
Thanks again everyone. I didn't have any sales on my actual birthday (Friday) but I made a sale last night and one this morning, so I'm happy...and happy fathers day everyone!!
