Hi there @dcdick A warm welcome to our community forums first of all.
Our new sales offers do change from time to time and I'm unable to tell you whether the next offer will be better tomorrow. It's a bit of a gamble in my opinion, but if there's anything we can help with please feel free to let us know.
I've joined the Plusnet Help Team as of May 2017. As such, I have a new forum account. Please direct any queries to @Gandalf. Thanks
