Well, I guess they ran out of stock real fast. Seems they didn't made enough for the launch. Also which one is better between the two stores?
here's something i found on elemental14's threads:
The Pi people can't be blamed. They did the best they could. 10,000 boards will have cost them about $250,000. That's a huge amount of money for six people to gamble - and until about 0800 on Wednesday they didn't KNOW how it would go. Getting a million boards produced for the launch would have been a huge gamble, they could easily have been left with 900,000 unsold boards that needed to be dumped.The surge of interest might have died down shortly after release time and the number needed could have been only a few times the original batch size.
