Yesyou are right that they might be smaller print versions but then ebooks are almost never same as the print book. The difference in page count may be attributed to n Font and size . I read somewhere that Georgia is 15% bigger than Garamond and if the font size is also changed then the page count can vary a lot. Formatting. Line spacing may vary. nPlease check if it is the same edition without any special editions generally have specifically mentioned so.
