Possible misprice by Argos.
I think the checkout is supposed to charge 19.99 for Gran Turismo and give Motorstorm free. Looks like it's giving both for free.
I don't know if this is a great price for an PS3 80GB as others have similar deals but these are in stock and there's no extra delivery cost (if you pick it up yourself).
I think the 40gb for 219 is a better deal but they do not seem to be in stock anywhere.
