I just verified here with my expense receipts from last year, $94.80 paid up front for 2 years of hosting (@ 3.95/mo for 24mos).
Set it and forget it.
As for the coupon code, I don't remember exactly, but it was most likely a google search for "bluehost coupon codes" or "bluehost promo codes"
Just did a search, found this site:
http://www.hostingz.com/bluehost-coupon.html -- you click the link on top and it forwards to bluehost.com, and has a nice red line though the 6.95/mo and drops it to 3.95/mo. Seems like this is a pretty common deal if it is still available.
I can only imagine after my 2 years are up, it will go back to 6.95/mo, and that may be what you were describing by people complaining of "sudden" price increases. That's just people that don't pay attention, IMO, and go "what is this 200 charge on my card!!?!".
< disclaimer > I am in no way affiliated (though, after looking at it, I might want to sign up for an affiliate account, $65.00 kick-back per sign up!!) with bluehost. Make your own informed decisions based on your need and market research. Bluehost has done wonders for me, but that may not be your experience. < /disclaimer >
