My previous question was about renting electronic textbooks (ebooks) online. However I'm interested in renting physical textbooks as well. Actually I like the latter books much more when I study. That's because I can put stickers, pieces of paper instead of electronic notes and bookmarks. I can also have 2 textbooks open simultaneously if needed.

So my question is what online Textbook services offer renting physical ebooks?
