LuLu.com is one of the largest online print-on-demand self-publishing companies. They offer a user-friendly self-publishing wizard and let users print any number they like, from one to 1 million copies. They offer three paperback binding options and two hardcover binding options. They also offer 14 different sizes of books and three paper options.
Self Publishing Inc.'s business has been running for 25 years, and a few years ago launched its online portal (selfpublishing.com). Depending on the method selected they are one of the least expensive options. SelfPublishing.com also allows authors to get an ISBN for their books, and helps with marketing and promotion. They also offer website creation and hosting services for their authors.
Arbor Services (arborservices.co) bills itself as the least expensive self-publishing service. They are geared for large orders and price their services on a case-by-case basis. Users must fill out a pricing quote form first.
Another option is to take the manuscript to a local print shop or printing services location like Kinko's or Office Depot. Depending on the requirements of the publication, this can be the cheapest option. This is also good for those who need to have something published quickly, as the turnaround time is generally fast.
