(self-serve regular unleaded - 87 octane)

It's almost like they kept racheting up the price until people started screaming, then backed it off a bit. Another interesting point is that it's $2.99 almost everywhere today - the usual 10-15 cent or so fluctuations you get between one part of town and another don't seem to apply anymore.
