wideman, thanks for the info. but when I read the delivery option. here is what is says:
"1.1. Date and time restrictions for ticket collection Each booking has a date and time limit for collection which is shown at the end of your Booking on the website and in the confirmation e-mail which is automatically sent to you. Your reservation will automatically expire if you have not collected tickets before that time. .
- If your Booking is made less than three (3) days before your departure date, you can collect your ticket up to thirty (30) minutes before the train departs.
- If your Booking is made between three(3) and eight (8)daysbefore your departure date, your tickets must be collected within 2 days of making your Booking.
- If your Booking is made between nine(9) and sixty-two (62) days before your departure date, your tickets must be collected within seven (7) days of making your Booking.
1.2. Date and time restrictions for collection of railcards
Railcards must be collected, at the latest, by the first day of validity"

so does this mean I have to pick up the ticket within 7 days of booking. But I won't be in Paris till end of November.

thanks
