Well, I was approved. It took about 4 businness days. I set a budget of $5 a day, and to my surprise received 48 emails saying my credit card was billed $5 for low funds. So I disabled the account and called Yahoo. They said they had no idea what went wrong but gladly refunded me, so no harm done. (They have great support by the way)
I suppose that the time depends of how much do you want to buy ... :-o It is a joke ... I think that the people dont want to wait very much time ... Two or three days will be a wonderful time ... :-o
