An anonymous tipster has leaked an alleged document detailing a price drop for the Palm Pre sold at indirect partners – only $150 after mail-in rebate. This rumored price drop will not be for an indefinite period of time, but from September 8th to October 31st, the Pre can be yours for the bottom-line price of $150. Given that the HTC Hero will carry a $179 price tag on Sprint, it may be safe to assume that the $150 Pre price will not only be available on Sprint, but could be available beyond the expected October 31st time frame. We will all know very shortly!
