Geez...

Would you rather of them given you an answer like "I dunno?" The online store is MADE for ppl like you. If you have any experience with apple products, you should know to pre-order online the first chance you get. Apple has been notorious with missing ship dates, but if you pre-order you can get the product ASAP.
I do understand your frustration with the express not being available, but remember, Apple Store employees have little to no knowledge of whatever Cupertino is doing with their stock of products.
