Felix, an 8 by 10 is $25. However what the Zuiderdam does is they force you to buy the whole sheet which is an 8 by 10, a 5 by 7, and 2 wallets. A good price if you want all, but if you only want the 8 by 10, not so good. When we were on the Westerdam we were allowed to buy the 8 by 10. I guess it depends on who is running the photo area, but the photographer at the desk simply cut off the rest and threw it away. I was not happy.
What upset me even more, was we had a coupon (previous cruiser), buy (I think) three 8 by 10s and get one free, if we counted the larger $40 sheet we had three 8 by 10s, but it did not work that way, we had to buy 3 of the larger sheets, and then we would get larger sheet free, we could not count the larger sheet to get a free 8 by 10.
