Half Price Addictive Drum ADpaks Discount Code

Did anyone get an e-mail for half price Addictive Drum  ADpaks? I got the ad but don't see a discount code anywhere. I clicked the go to half price Addictive Drum  ADpaks button but it never showed any code. The sale ends today and I was going for the retro pak. Please let me know if you have any info. Thanks
