I commenter on my site just pasted an affiliate code, for which he’ll return all the money he gets. You save about $97 a year, which is pretty darn nice.
Simply use the promo code RUBY_ON_RAILS at http://www.dreamhost.com/r.cgi?ruby_on_rails for the discount.
Original comment here (so you know I’m not spamming):
Hope that helps some people
