Amazon cutting its 20% pre-order discount for Prime members

Starting August 28th Amazon Prime subscribers will no longer recieve the 20 percent discount when pre-ordering games. Pre-orders will now come with $10 of in store credit.

There is a catch with this credit though.

Once you have pre-ordered your game there is a mandatory waiting period of 35 days to recieve your $10. The credit will be emailed to you, and is only valid for 60 days after activation.
