The sale will be conducted at Apple retail stores as well as the online Apple Store.  Apple has posted a teaser at their online web store:

What to Expect
Previous year events have offered buyers modest discounts on select Apple products including Macs, iPods, and accessories.  Apple is likely to offer discount on the iMac and the MacBook models as they did last year.  Buyers were not allowed to stack the special event discounts with the education discounts last year and Apple will likely implement the same policy this year.

Last year's event had the following noteworthy discounts.  Special event price listed first followed by discount amount in parenthesis:

• iMac: $1148 ($51), $1398 ($101), $1698 ($101), $2198 ($101)
• MacBook: $1048 ($51), $1198 ($101), $1398 ($101 off)
• iPod Classic: $228 ($21), $318 ($31)
• iPod Nano: $138 ($11), $188 ($11)
• iPod shuffle: $68 ($11)

Apple also discounted numerous accessories and other Apple products including the Apple Wireless Mighty Mouse ($11 discount) and networking products such as the Airport Extreme Base Station ($21 discount).
