With relation to a standard free or full member, promo-credits are similar to standard credits.
A given number of credits equates, promo-credits cannot be used to purchase items as gifts for other members and may not be traded back to an IMVU re-seller for actual currency.
Promo-credits used to purchase a virtual product are exchanged into "developer tokens", also known as "dev tokens".
Credits can be transferred back from IMVU to actual currency for developers accounts only.
The credits are used by members to purchase virtual items like fashion pieces (hair, clothes, skins, and accessories), pets, and 3D scenes such as homes, clubs and open landscapes.
Furniture can also be purchased the same way and placed into unlocked rooms, but there are also rooms that have some furniture included in them as well as locked rooms that include furniture that cannot be removed.
Promotional credits, abbreviated to "promo-credits" or "predits", are a second form of currency distributed to members by IMVU and can be obtained by participating in various "Partner" promotions as well as a few activities the IMVU provides.
Many IMVU users are content creators, creating and selling products in the IMVU catalog.
Users also devote time to customizing their individual homepages, setting up public and private rooms, creating and participating in user groups (similar to forums but personalized via the owner), and participate in the Community forums.
Additionally, there are numerous user produced third-party websites providing additional forums and resources to the IMVU community.
IMVU contains its own economy with a currency system based on IMVU "credits" and "promo credits".
A third form of currency also exists for creators, known as "developer tokens", which are earned when a user purchases an item with "promo-credits".
Credits can be purchased online using actual currency directly from IMVU.
Credits may also be purchased on IMVU gift cards available from retail outlets such as department stores.
