Amazon offers its Prime members Crisis Core: Final Fantasy VII for PSP
with free shipping
. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's tied with yesterday's expired mention (which was via in-store pickup only) and the lowest total price we've seen for this game. (It's also a current price low by $5.) Note: It's "temporarily out of stock," but it can be ordered at this price for delivery when available.
Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months.
