When it was still active, prospective members could join the Mosaico Book Club by visiting the club's website. However, the site was last updated in 2013, and the address, ClubMosaico.com, redirects to the domain's page on RankOffSite.com, as of 2015, indicating that the Mosaico Book Club is likely no longer active. Additionally, subscriptions to the club are unavailable on book club search engines such as BookClubUniverse.com.
The Mosaico Book Club was a service that offered discounted prices on books written in or translated to Spanish. Upon joining, members received four books of their choice for $1 per book and also received free accessories, such as an umbrella and a tote bag gift set. After that initial purchase, members could purchase additional books at the club's discounted prices, which it was able to offer because it acquired the books directly from the publisher instead of from a retailer. Mosaico offered books in various genres, including fiction, nonfiction, romance, health and beauty, children's books and cookbooks.
In addition to the deals on books, the club provided other benefits, such as a member-only monthly magazine, free excerpts from books, reviews and recommendations from fellow club members, and various special offers. Additionally, Mosaico's members also received discounted prices on books from other online book clubs.
