Hope this title is clear enough. I can figure out how to buy the tkt on the Eurostar site, but not how it gets in my hands. Is there a willcall window or can I print it out?

I picked mine up at at "ticket" machine.

I think you need the confirmation number and the credit card you used to book. It was very easy and the ticket just printed right out.

I don't recall a print from home option.

Do these ticket machines accept magnetic-strip-only US credit cards?

Carol--thank you.
Gregg, I have the same question.

The ticket machines in London took my USAA Visa which is your basic American card, no smart chip. This was around 10 months ago.

Can you pick up Eurostar tickets at places OTHER than Eurostar station: such as other train station in France or at a SNCF boutique shop in cities in France?

there are also 'live' ticket windows if you do not wish to use the ticket machines.

I tried to pick up a ticket using a European Amex card (which does not have a chip) and it didn't work. Those with other cards didn't seem to have a problem. If it doesn't work, you can pick it up from the ticket desk (leave enough time, there may be a queue). It's essential to have the credit card with you that you used to book the ticket.

Machine would not take my card in London Waterloo( 3 yrs ago) , but I just went to ticket window and no problem.

Thank you all. I plan to use the window pickup.
