Subject: [PATCH 4/4] Make text message price dependent on date
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So we don’t have to deploy a change on a Saturday.

In the future this could pull from the rates in the database, but while
that code is shifting around I didn’t want to touoch it. We’d also have
to think about caching so as not to have a non-authenticated route
hitting the database.
