I was in my thrid, or fourth, day of trial on these programs and was seriously considering buying them. Then I received my monthly newsletter from Afterdawn and it had the same $10 off promotion.
Needless to say I made my purchase about 5 minutes later and within a minute from that I had my keys. I saved them in 4 different places (i reload my PC from scratch every two months).
So far I am very pleased with the functionality, and ease of use, of these programs.
Edited to add:
"Is this a rebate or do you just pay 10dollars less."
You pay $10 less.
