Good spot! i was looking for this too. Not sure £5 for 5 courses is great value, but maybe it'll include some other stuff too.
I don't think it's too bad, seeing as they run for what about 320msp a course if you buy individually which works out at about £2.70 each. Best way is to grab em in the multi couse downloads they do but I don't think they usually come out for a while.
