Downloading mountain lion for bootable disk
I just bought a macbook pro and it already has mountain lion on it (10.8.2). I am planning to install an SSD into the mac to get better proformance but I do not have a data transfer cable, plus I want to do a clean and fresh install anyways. I went to the app store and the mountain lion costs $19.99. Since I already have the update, is there a way I can get this free somewhere, preferably legally LOL.
MacBook Pro, OS X Mountain Lion (10.8.2)
