Congrats on getting the book published. I noticed the Amazon link doesn't offer the book as an ebook. Many are buying their books that way now. I wrote and self published for years and am getting back into it. You should consider offering it in that format as the price point would be cheaper for your readers and your cut (if between 2.99-9.99) would range from 60%-80% depending on the bookstore.

You can upload the word doc direct to amazon kdp and the other book stores. Or use an aggregate such as https://www.draft2digital.com/ who will charge 10% of sales and convert both to mobi and epub and get your book in many stores such as Nook, Kobo, Apple etc. If you can figure out the formatting for Smashwords they also can be an aggregate, but have their own store as well that pays out 80% for in store sales. Smash also allows you to issue coupons to your potential readers for promotions in their store.
