I too was expecting the usual, but have been pleasantly surprised - well, my other half actually as she did the ordering. No difficulty with logins and passwords etc.
All tickets we required secured and paid, and email confirmation received.
Note: there is now an option to have electronic copies of your tickets emailed from the ACO and then print them yourself, therefore removing the need for shipping etc. so no nail biting uncertainty as to when you will receive them. There are stipulations as to exactly HOW you print them (paper size, orientation etc.) presumably to be sure the barcodes etc. are readable but won't challenge the average home printer filled with A4 paper. I have selected this option.
Haven't received the actual electronic ticket files themselves yet, but am guessing the ACO guys and girls at the ticketing operation are a bit busy today. So far so good.
