Tired of cosplaying the same character a million times? Or just moving on from cosplay in general? Then it’s time to sell or trade off your cosplays to the next person at the Cosplay Marketplace! Or maybe you’re new to cosplay or want to give it a shot? Stop by to purchase some second-hand cosplays! Peruse the different items available from different cosplayers, whether it's full cosplays, props, wigs, or even shoes!

Prohibited Items: Contact Lenses & Undergarments

Prohibited Items:

  • Contact Lenses
  • Undergarments

Want to Sell?:

  1. No prior signup is necessary, just show up as early as 10:00 AM, Grand Ballroom A, and tell the front door attendant you want to sell! Tables can be shared between cosplayers; we just suggest marking what is yours. All spots are first-come, first-served! Feel free to come at any time during the event.
  2. Please arrive early to set up! It makes the experience easier.
  3. All items are subject to a brief search by our staff to ensure that the prohibited items are not sold. Please do not harass the staff if they stop you from selling items against our policy.
  4. We will also provide a changing tent for your table.
  5. Feel free to bring a coat rack or dress form to display items.

  1. All clothing must be cosplay-related. If it is not, you will be asked to put it away. (Examples being jeans, t-shirts, etc...)

  4. NO food or drink, hotel, or convention center provided or not, within the event.
  5. Only second-hand is allowed. This is not a space to sell new products you created or on behalf of a company. (This does not include cosplay you purchased/made but have not worn.)

  3. We HIGHLY suggest not letting people try on wigs due to sanitary reasons. However, we will not be policing this, and it is due to your comfort on behalf of the customer and seller.
  4. Label your things clearly with a price, “TRADE ONLY,” or price and trade. Make it clear what you want for this piece.
  5. If you have any cats, dogs, or other allergy-inducing animals that may affect the pieces, please label them clearly.

Garage Sale

SUNDAY - April 26, 2026
3:00 pm - Grand Ballroom CD, Convention Center

Let us assist you with your spring cleaning as we provide a space for a nerdy garage sale and swap meet!  Like the Cosplay Marketplace, table space is first-come, first-served and doesn't require an extra cost outside your general badge admission.  Whereas Cosplay Marketplace is for cosplay items, the Garage Sale is for everything else nerdy; including but not limited to manga, DVDs, figures, charms, etc.  Read on to learn about participating!

Prohibited Items:

  • Anything 18+ or NSFW
  • Digital item codes (all inventory should be physical and present)
  • Bootlegs (please refer to #1 below for the extensive list)
  • Undergarments
  • Contact lenses
  • Items autographed by current guests at the convention
  • Nothing created from Generative AI
  • New for 2026 - Pokemon Trading Card products

 

Want to Sell?:

  1. No prior signup is necessary, just show up early at Grand Ballroom CD at 2:00 PM and tell the front door attendant you want to sell! Tables can be shared (we encourage it!), but we just suggest marking what is yours. All spots are first-come, first-served! Feel free to come at any time during the event.
  2. All items are subject to a brief search by our staff to ensure the prohibited items are not sold. Please do not harass the staff if they stop you from selling items against our policy.
  3. Please arrive early to set up if you have a lot! It makes the experience easier
  4. Set-ups should not mimic an artist alley set-up or be used in a way that is similar to an artist alley table.  Essentially, an artist alley hopeful should not treat this event as an artist alley and avoid bringing the same amount of product they would for this.  This part of the convention is mainly for selling and trading nerdy memorabilia that attendees want to re-house, not for new product sales.
    • Additionally, you can bring original products featuring your art, but they must take up only a small amount of space. If we feel the display is too reminiscent of an artist alley booth, we will ask you to disassemble. This choice is at the discretion of the staff.

Rules:

  1. Regular nerdy clothing can be sold, such as graphic T-shirts.  Anything cosplay-related should be used in the Cosplay Marketplace instead.
  2. Upon leaving the event, you agree that Anime St. Louis is not responsible for the prices, trades, or exchanges done within the event.
  3. Anime St. Louis is not responsible for any exchange of monetary value. The transaction is the sole responsibility of both parties.
  4. NO food or drink, hotel, or convention center provided or not, within the event.
  5. Only second-hand is allowed. This is not a space to sell new products you created, on behalf of a company, or to scalp high-demand, unopened new items.
  6. We take theft very seriously. Theft results in immediate removal from the marketplace, future swap meets, and the possibility of badge removal from Anime St. Louis.
  7. Report suspicious activities to the staff members at the event.
  8. Products you purchased in the Garage Sale 2026 or Cosplay Marketplace 2026, you can’t resell at Garage Sale 2026.
  9. ABSOLUTELY NO BOOTLEG PRODUCTS!
    • What is a bootleg?
      • Unofficially produced merchandise passed as official or with official materials unlawfully added, often made with stolen art and poor-quality materials.
      • This includes, but is not limited to:
        • Knock-off figures
        • Official art re-used and made into buttons, cups, posters, etc.
        • Burned disks & flash drives
    • Our staff will do their absolute best to keep a vigilant eye out for bootleg materials. Unfortunately, we can't always spot it during our searches. So please make sure you, as a buyer, stay informed and buy at your own risk!

Guidelines/Suggestions:

  1. When in doubt, ask questions about the item you are interested in.
  2. Keep a list/inventory of everything you bring up for trade or sale. Keep track of what you sell/trade and your transactions.
  3. Label your things clearly with a price, “TRADE ONLY,” or price and trade. Make it clear what you want for this piece.
  4. If you have any cats, dogs, or other allergy-inducing animals that may affect your stock, please label them clearly.
  5. Always ask before handling items.
