Apple could be planning to launch its annual Back to School sales promotion within the next two weeks. Apple Stores, according to several employees, will be changing the front of store glass window displays overnight on June 30th. This is the usual timeframe in which Apple launches a promotion to boost Mac, iPad, and iPhone sales in anticipation of the new school year in the fall.

Last year, the Back to School promotion consisted of $100 App Store gift cards for Mac purchases and $50 cards for iPad and iPhone purchases by students with their Student IDs. Of course, this June 30th window change could be connected to another promotion or a new product, but based on the timing, the Back to School program being in the wings seems most likely.
