Learn English – the meaning of “I’ve gotten over __ recently”

The trick to understanding this advert comes at the beginning:

Here’s introducing iDiva: Five Magazines in One

So the publisher is saying their magazine is the equivalent of five other magazines.

Also they are selling the first issue at a cut down introductory price:

At an introductory price of Rs 5 per copy

So, in their mind, the magazine is cheap even compared to a normal magazine, but because it is five magazines in one, the cheapness is exaggerated by that multiple, so this deal is five times better than any normal discount on a magazine, i.e. five times over.

None of Webster, ODO, Collins, or MacMillan lists "At top speed; frantically" as a possible definition of "head over heels". They only note the two definitions that the OP is familiar with. However, I can imagine without any great difficulty that frantic top-speed running could well involve chaotic stumbling and tumbling, and vice versa. So, it's not all that much of a stretch.

He looked scared, and that was no wonder, because head over heels after him came five other boys.

This could easily have been written by Stephen Fry with wholly different connotations.
