How long is the sale on BEC going to last?

I want to get it, but I am wanting to wait until MM is over before I commit in case there is something I want from it, too.
Logos has an irritating habit of shutting down sales a day or two before I am ready to act. They just lost about $500 because they cut off my 15% off discount on base package add-on bundles about 24 hrs. before I was prepared to get the ones I wanted.
