Q: How do i download free pages and numbers for my new iMac?

Look in the Purchases List. The iLife apps should be there to accept and the iWork apps should be there to download.

I have just purchased my first 27inch iMac which is great. However when i try to download pages and numbers from the App store i am being asked to pay for the download.

How do i download these apps for free?   

OS X Mavericks (10.9.2)
