Here is a copy of what I recived:
Hello from DKPSystem.com!
In celebration of our first full year, we're doing something we've
never done:
We're lowering our prices!
Here's the catch, each day, until June 1st, the price goes up.
Today (for the next 45 minutes) all of the packages are %75 off! This
applies to renewals, upgrades, and of course, new signups! Tomorrow,
the packages will be 67% off, and this trend will continue until June
1st, when the prices return to normal.
So the sooner you sign up, the more you'll save!
Thank you for your continued support, and together let's make this next
year even better!
