Congratulations Ruka, your great deal also says that either the seller is taking a big loss - which I doubt, or the true cost of the PRS-300 is less than we think.
He may not be making as much profit as he would like, but he can't stay in business selling below cost.
Maybe Sony has room to drop the MSRP for all of the readers. Especially since Amazon just dropped the price of the Kindle 2.
If we, the consumers, get really lucky there will be a price war. Who would win? The multinational electronics corporation, or the mega e-tailler.
