An online ebook store is a digital platform that allows customers to browse, purchase, and download electronic books directly from the internet. 

It offers a convenient and accessible way for readers to access a vast selection of digital content. Investing in an online ebook store can be a lucrative full or part time business opportunity as it provides low overhead costs, global reach, and the ability to offer a wide variety of titles without the need for any physical inventory. 

Additionally, ebooks have become increasingly popular, providing a growing market for this type of business.
