Just got an email about it today,
It sends a link to your email with a link to the scratch card when you can get up to 100$ off your purchase (although there's only a total of 15 $100 codes being given out).
Up for grabs there are:
* $100 off (only 15 available)
* 50% off
* 40% off
* 30% off
* 20% off
More likely than not, you'll be getting a 30% off code.
I've grabbed some codes for you guys:
