How do I know when will the be special saving I can get in Apple? Specifically, when are items discounted and why are they discounted? In addition, I would preferably like more information about the beats solo 3 and the MacBook Pro 12 inch.

Usually after large holidays are when you can get deals. Christmas in particular, when last years models haven't sold and new years are coming in.. Although apple is always over priced soooo, not many deals to be had.

I would check CNet for reviews of Apple products. They seem to be unbiased and are technically very sound.

Holidays are usually the best time to grab a discount.
