Consumers can purchase mermaid tails for swimming online from specialized mermaid tail retailers such as Fin Fun Mermaid, MermaidTails.net or Mertailor. Mermaid tails are also available through auction sites such as eBay.com.
As of March 2015, individuals using MermaidTails.net can browse through several special site features that explain the purpose and function of the company's mermaid tails. For example, one section outlines the reasons behind the company's design choices for its mermaid tails, such as the special durable material that allows the swimmer to wear the tail for extended periods of time or the unique fin design that allows for easy access to the feet and increased user safety. Individuals can also view listings for various products on the site in addition to the mermaid tails for swimming, such as accessories and swim suits.
The Mertailer website contains a section for mermaid tail purchases as well as a section for tail rentals. Each listing contains a picture of the item along with details about pricing and unique features. Listings for mermaid tails on eBay.com also contain pictures and descriptions, though the quality of both varies from seller to seller. In some cases, an individual may need to contact the seller in order to inquire about specific product features.
