There seems to be, click on the icon Buy Book, and you are taken to The Book Depository. I am not familiar with that particular site, although I soon will be, but I assume they have a wish list function as Amazon does.
Just checked, they do have a wish list.
There is also an Amazon Wish List extension for the Browser Google Chrome, if you use Chrome and have this extension there is an Amazon 'a' logo in the upper right. If you are looking at an item in the library here, and you click on that logo, the item is added to your Amazon wish list, with room for 500 characters of comments.
