I am using digitalocean . It is a great vps server and its price is good.
Till now I refer more then 30+ refer by a single post on my blog.
It gives refer bonus for use in their hosting purpose.
By this affiliate marketers not promot this. Mainly every blogger promot them who gives good amount.
By this step digitalocean promoters is few . it is a cheap and best vps hosting .
I see many hosting companies that give digitalocean's 5$ plan in 25$ .it is a big difference in amount but features is same.
If digitalocean give amount for sale which can be redeem in paypal or bank account it is good.
