Do you get student discount on top of the sale thing today on a Ipad?

My understanding is that you get ONE discount -- probably the one that is largest. The ad has some fine print at the bottom that says:

"Promotional pricing cannot be combined with any other offers."

Tgara is likely right - but the easiest way to find out is to ask Apple Sales directly. :-)

Call the stores and ask.
