In iBooks,what does it mean when it says: you have already purchased this item. To download it check available downloads in the store menu?

Answer 1

Apologies if I seem rude but isn't it obvious?
you have already purchased this item means you have already purchased this item - you don't need to buy it, you've already bought it.
To download it check available downloads in the store menu means to download it check available downloads in the store menu. So if you look at your top menu bar (in your iTunes programme) select the Store and from the menu that appears, select Check for available downloads. My guess (and I realise I'm risking my reputation here ) is that when you click on that, you will see a list of the items you've bought which will include anything you haven't yet downloaded to your iTunes. I assume there will be an option with that list to download those items.
I would like to thank the person who thought of the idea of taking different words and putting them in a certain order, so that those words form a sentence, and that sentence can then be read by other people and those people understand. Genius!
