A detail to note is that the
credit card company will be picking up some, if not the majority, of the cost of
any "reward" item acquired through those programs -- they buy the "reward items" from the seller (in this case, Sony) and offer them through the rewards program according to the terms
they (the CC Co.) choose. It's not
quite the same thing as if SonyStyle were offering PRS500s for $60.
Just a detail.
