The Last Supper Tickets just went on sale (midnight Pacific time) for September. They are extending times because of the Expo 2015 in Milan. For those wanting to go in August or September, now is the time to buy online. (a few June and July dates available also). Go to http://www.vivaticket.it/index.php?nvpg[tour]&id=744 or just http://www.vivaticket.it and find Cenacola Vinciano. I registered ahead of time to be ready, and I really suggest you do that if you are buying next month, etc. For September, you might just want to try to grab your seats and then fill in the registration.
Choose English is in the top left corner of the page.
To register, go to top right corner. I put in my driver's license for ID instead of passport number, and it was accepted just fine.
To buy: Click on the orange Buy button to the right of Cenacola Vinciano. Next page, push Buy again. (before you leave this page, notice it shows when tickets will become available. I was waiting for the June 4th date for my September tickets.)
The next page has a calendar of tickets. You want the orange squares on the calendar to find an open seat. Click to the right of the month until you reach the month you want. Click on the day if it's orange and you will get a chart to the right, with available times. Hovering over it tells you how many seats are available. Click on the time and you will get a new page with a seat selection chart.
Sometimes it gives you two zones (the ingressi on the left.) As far as I could figure out, the first one is for automatic seat selection and the one below is for manual seat selection. I just did the first one, so no idea about the other. After the zone, to the right, it tells you how many seats. To the right of that, it gives you prices. I am not a student or the other categories, so I chose the first one, which is 8 euros total for each ticket. (Since the options are in Italian, I suggest you check before your date comes up or before you select tickets. There is also a FAQ link at the bottom of the page that gives info on payment methods, etc.) Under the ticket price, select how many tickets you want.
Below this chart is a verification code you have to enter. This is where I had a little trouble. I put in the code, but it gave me an error message because my internet explorer asked me if I wanted to proceed and I didn't notice that. I had to allow the option to proceed with internet explorer (I have my computer security tighter because of pop-ups). After putting in the code, push the orange Buy.
The next page gives you the total. If it is right, push the orange Add button. (my two tickets were 6.50 euros apiece/13 euros for two + 1.50 euros per ticket for fees for a total of 16 euros (the fee was added into the price so the price I saw was 8 euros per ticket).
The next page shows what you ordered and gives you one hour to confirm. If I had waited, a better time actually came up for my day, but I was worried about missing out. I might have waited to confirm longer had I known different times were still being added. But when you are sure about your purchase, push the orange Confirm button. Make sure--tickets are non-refundable.
After confirm, it gave me the options to give my credit card information. Since I was using Visa, I have the Verified by Visa ready (I never remember my password but it lets me pick a new one every time without leaving the buying process.) It would be a good idea to check the FAQ for buying options so you know if you have the right card, etc, but you can get to the page where you have one hour first, and then open the FAQ in another window if you want to get the right day and time first.
After I added my info, it was accepted, and a page came up with ticket confirmation. Use the print button on the page to print to take to the ticket office the day you go. You need to be there at least 20 minutes ahead of time so keep that in mind!
