I just called Sony (via Skype - as I live in Poland) and got 10% off for the reader and 15% for the cover.
Not sure if I'm gonna get this, anyhow: my english sucks (I even probably misspelled my email address, so I don't have a confirmation), I'm not sure if they noted the address down correctly, the shipment is to the friend's aunt (she's coming to Poland for Christmas and she's supposed to take it with her) and the item has to be delivered to her before December 15, in order to be there before her flight.
But I hope there'd be a happy end in the end of this story
