I'm leaving the country for a long vacation on March 21st. I want to make sure that I have a couple of ipad 2s for the trip. I don't mind ordering and waiting as long as I get them before the trip. And I would prefer not having to wait in line, though I'll do it if I have to. Any guesses as to how long the shipping time would be if I ordered from Apple tonight at 1? How much of a delay if I go for the free engraving as well?
