The first month free is not really "free" per say.

You pay TWO MONTHS upfront, they give you the 3rd one free.

They are basically giving you the same deal they are getting from the datacenter they are reselling from. I know this because I was one of such resellers until we got our own hardware, etc.

I don't think you will find a TRUE FREE MONTH of service, what you could probably find is a pay one month get one month free, check the offers section and always read the fineprint.
