Amazon.com has PlayStation 4 consoles in stock at the standard retail price of $399.99 with free shipping.
Based on previous restocks on Amazon, chances are the PS4 is in limited quantities. Jump on it now if you want one to play upcoming exclusives like this month's Infamous: Second Son.
(Reminder: all new Amazon accounts are eligible for a free 30-day trial of Amazon Prime, which provides free 2-day shipping. College students with a .edu email address qualify for 6 free months of Prime.)
