Bluehost Rebate Question

Hi,

I am planning to start a blog, and Bluehost seems like the best option. I wanted to use a rebate on Bluehost, and there were plenty out there. I found some for $50 and some for less. Are they just going to cheat you, or will they actually pay you money? I would appreciate if you could show me some that actually work.

I understand that these "rebaters" give you a portion of what they earn through getting their affiliate commission. Are you allowed to sign up as an affiliate and buy through your own affiliate link- receiving a commission? Or is that not allowed?

Thanks for your help.
