When I view the initial buying page for an iMac it say for my post code (which is in the US) it will be delivered using Free 2 Business Day shipping and arrive on June 9th. But then if I proceed to actually place the order then this changes (though the post code is still the same) to an estimated delivery date of June 14th to 16th. If I go back to the first page, it says June 9th again. Whats this about? Anybody else seeing the same problem? How can I get the Free 2 day business shipping I was shown on the first page?
