Pull Tabs - Quest for the Win Only-ies

In pull tabs - a face book application I have talked about on Where Was I before, you have to win a certain amount of Win only prizes to move to the next level.

Right now I am on the last level of pull tabs (though I hope they add more levels) and need only three different Win Only prizes to finish the game. Two are on a ticket called Lucy in The Sky, but I am working on the win only Piano before I try for the win only-ies on the Lucy card.
I have been buying 25 Night at the opera cards, each day, for the past month. And i still have not won this stupid piano!

I see people putting the Piano W/O in the market place all the time, but they was 65,000 or more credits for it! AS IF!

*pout* Why do they get to win more than one piano when I still haven't won mine? it's not fair! *stomps foot*
