Then you pay more and get it somewhere else. Not sure why anyone gets digital anymore when you can sell back physical copies for money.
Basically I get the 20% from amazon, pay 49.00 Play the game for a couple weeks/months till i get bored, sell it back for 25-$30. It's like i only pay $20-25.
To this day, the only game I've resold or wanted to re-sell was Killzone: Shadow Fall.
I'm confident in my purchases. I'd rather save the shelf space and not have to change disks.
