Those attending the opening of Apple’s new San Francisco retail store this Saturday will be able to purchase something very intriguing: US$249 gift bags containing over $600 worth of unknown Apple products. As expected, Apple isn’t saying what exactly is in the bags, but they did say some will include “a special surprise.” According to an email sent out by Apple to announce the grand opening of the store, only 200 of the gift bags will be available Saturday. If you attend the store opening and purchase one of the gift bags, please let us know what was inside.
