Here is a transcript from my conversation online with the Apple store:
You are chatting with Eda M, an Apple Expert
Hi, my name is Eda M. Welcome to Apple!
Eda M: Good afternoon
You: Hi Eda.
Eda M: How may I help you today?
You: I ordered a copy of Snow Leopard through the up-to-date program (i had to send in forms as the online service wasn't working) and I was just wondering if I recieve an email when it ships or if there is any way I can check the status of my order?
Eda M: You will receive an email when it ships.
You: Great. Does it aim to deliver by the 28th or just ship by the 28th?
Eda M: If you pre-order it should be delivered on the 28th.
You: I used the up-to-date system - is that the same as pre-ordering?
Eda M: Let me double check on that please.
You: thansk
You: thanks
Eda M: You're welcome.
Eda M: For the Up to Date Programme, availability will be in September.
You: oh. ok. Thanks for your help
Don't know if he misunderstood, was not well informed or if he is speaking the truth. God knows!
