How do I find my purchased OS X 10.9.2 which was accidentally deleted from App Store? I have accidentally deleted my copy of OS X Mavericks 10.9.2 from the App Store in the  purchased section under my account.

Is there any way I can get it back again without paying for a second time?
You can´t really delete your purchases - but you could hide purchases.

Apple has a Support file for this case.

You have to:


Open the Mac App Store.
Choose Store > Sign In, then enter your Apple ID and password.
Choose Store > View My Account.
Click on View Hidden Purchases from the Account Information page. 
From the Hidden Purchases page, locate the app you would like to unhide.
Click the Unhide button.
