This promotion actually ended a couple days ago. We have a new one listed on our website here: https://www.knownhost.com/specials.html.
Like always this coupon is valid for existing customers towards the purchase of a new VPS account. Please let me know if you have any questions.
Yes that is a good question.
In 2008 all customers who have taken advantage of this promo, their price will automatically be increased to what the actual price of VPS XL is plus the control panel and +64 MB of RAM (fantastico, rvskin, powerpanel). If you wanted to take off the extra RAM or anything like that you will need to notify us.
