From 1\7 for 3 months MB are offering the above discount (code SC20) if you pay the whole amount up front. Funnily enough I only enquired about a plan a week ago and was told there were no deals on offer! Glad I waited a week. Seems to be a few glitches online at the moment but you've got 3 months to sort. Worthwhile if you have a big expensive service coming up.
