What is Cosmo's Club?

Cosmo's Club, named after our friendly dragon mascot, is a discount program designed for parents, teachers and students to help promote learning made fun. Cosmo Club members receive a ten percent (10%) discount* on all school related purchases and rentals. That means you can you can use your card to save on all costumes and accessories for plays, book reports, special events or themed days (Civil War Days; Renaissance Days; Colonial Days) which many of the schools now incorporate into their curriculum.

Does it cost anything?

Absolutely not. Becoming a Cosmo's Club member is 100% FREE. Costume Castle has been serving the South Orange County area for over fifteen years. We understand that education isn't cheap, but with the largest selection of costumes and accessories at low prices, we are doing our part to help make learning fun and exciting while keeping it affordable too.
