But you still have to pick it up in person.
They’ve had a similar ordering system for a number of years. The new website makes it easier. You still need to know the license number of the car you will be driving, which makes setting up an account prior to going to Europe difficult. It does sound like part of the new system records a code from individual bottles so that the Abbey can trace back bottles found in retail shop, and cut off buyers who are reselling. This may actually make the beer tougher to get for Americans.
I think I have still have two bottles in the cellar that I bought a few years ago. I came to realize that St Bernardous 12 tastes about the same and is so much less expensive and easier to find.
