All of the reports that I've read say it can take up to 72 hours to get the email from Apple with the code. Apple is laying the blame for the delay on the demand... but that doesn't sound right to me. After all, if the demand is high, it's because a lot of people bought new computers since they were announced on June 11. Apple should have been very aware of the number of units sold, and therefore should have been prepared for the demand.

That said, though, Apple chose not to handle it that way and, apparently got caught with their proverbial pants down. Apparently, patience is the word of the day here. It's only been some 48-50 hours since Mountain Lion was released...
