Amazon (NASDAQ:AMZN) is selling textbooks and other items to students at Purdue University, the University of Massachusetts Amherst and the University of California Davis.

Amazon is operating co-branded websites for the three universities. Students of these universities that are part of Amazon Student Prime can receive next-day shipping on items. The company plans to have distribution centers on the campuses that allow students to pick items up from coded lockers, The Wall Street Journal notes.

Students that don’t have an Amazon Student Prime account, which costs $49 a year, can still get next-day shipping on items related to their courses. The deal between the online retailer will have it paying 0.5% to 2.5% to the universities for purchases made through the co-branded website, WSJ notes.

GeekWire took a look at the Amazon Purdue Student Store and found that it’s being used for various needs. Students are using it for class materials, cleaning supplies and video games.

AMZN shares were up 1% as of Monday afternoon.
