The page here doesn't really mention that after the first year for dirt-cheap you're locked at yearly payment rate for CDI plan unless you then pay $50 to downgrade to monthly payments. In other words, after a year of 777-promo you have to cough up $119.40 for the next year unless you at that point pay an extra $50.
All in all it's still not a bad price, and you can use the year to save up for that $119.40.

(in case you're wondering, the topic of predatory referrals has been a hot topic around here -- and since DH doesn't seem to mind it I figured what the hey, let's all jump in on the bandwagon! -- sign up with Dreamhost and you, too, can prey for $100 referrals!)
