To my best knowladge is the Webhosting offer a free gift for only 1 year. You buy x5 and get 1 year free webhosting.

Hello Eric,

I am sorry that you are not satisfied with our program. 
We can not cancel your webhosting service: you have 4 months time to activate it after you have purchased the software. If you fail to do this, it expires. 
Please feel free to follow the instructions Andre kindly posted if you do not wish to receive our newsletters anymore. 
Thank you!
Samantha
