The discount is over, the each day a new 10 apps are available and we're now on day 2.
Also Deozaan - the Market and it's compatibility checks are really annoying. If you do any tinkering with your phone then it'll often get confused and say an app is incompatible when in fact it runs perfectly. That said there are modded versions of the market app out there that disable the compatibility check, and the geographic checks so an app is always available.
