In case you haven't heard, Amazon is offering a very cool offer to some customers - buy a kindle but only pay 20% of the price at checkout and then pay the balance in four monthly installments. To see if you're eligible, go to a kindle's page at Amazon and look for the orange banner near the top. It is limited to one per customer. For me, it is offered on all of the current kindles - regular, Paperwhite 2 AND the Voyage.
This is is pretty huge if you want a Voyage but are balking at the high up front cost.
