i'll give you $8 paypal gift to ship me FF: TA2, assuming it is mint and complete (which amazon also requests you do). but i guess maybe not as you have no feedback.
The others you might be able to get some good value for if gamestop has a stacked promo like trade 4 get $20 or 40% more or something but you would have to wait i think (it might have just ended).
of as you said wait till amazon has a deal.
