Global E-Commerce Mega Marketplace (GEMM)
Global E-Commerce Mega Marketplace (GEMM) is a music marketplace with a searchable user-submitted database of recordings for sale dating back to the early part of the 20th century. It features comments and descriptions of releases in a wide range of genres and types of media. GEMM was started by Roger Raffee and Jim Hall back in 1994. GEMM was the first marketplace site on the internet.
GEMM rates sellers from one to five stars based on the performance of each seller. If a seller has what the customer orders and all goes well with a purchase then the seller's rating automatically is positively affected. If the seller does not have what was ordered or if there are any subsequent problems with the order then the seller's rating is negatively affected. Customer feedback is also available to be viewed but it does not affect a seller's over-all rating.
GEMM processes customer payments and forwards funds to the sellers. GEMM guarantees all customer payments. GEMM accepts all legitimate forms of payments from customers, credit cards, checks/cheques, money orders, wire transfers, Paypal, etc..
GEMM is short for Global Electronic Music Marketplace, which has been a marketplace catering to buyers and sellers of phonograph records and CDs, but the site covers all music-related formats from vinyl to CDs, cassettes, sheet music, 8-track cartridges, books and videos. GEMM is changing it's name to Global E-Commerce Mega Marketplace in anticipation of expanding in to other collectibles.
The site enables collectors to track down rare releases for sale as well competitively priced items. The database can be arranged by artist name, title, record label, release date, genre of music, and the seller name. The comments and descriptions of items are also searchable.
