Unity Through Torah is an Ontario non-profit and does not sell seforim. Real purchases of Rambam HaMevuar stay with the publisher. Here you can rehearse selecting volumes, a no-charge “checkout,” and seeing entitlements in your library — then open Kavua (signed in with the same email) to activate or redownload on device. No payment is taken on this site.

Start a trial here. This site signs in with Google first. Kavua then opens, and signs in with Google only if it has not already. If this account has not already used a trial, or a trial is already open, Kavua downloads the seforim for that period.
