I will have paid for it, I copied this text from the online Apple Store:
"For pickup items, you will be billed before your item is ready for pick up. "
Hmmm, well I'm sure if you don't pick up within the designated pickup time, your money will be refunded. Point is, April 7 is three weeks from March 16. That's just not a reasonable amount of time to hold an item for this type of pickup.
