I've been out at multiple locations around the world searching for meteorites and have been buying and selling meteorites on eBay since 2007 under the moniker
spacerocks, mainly for evolving my collection (not as a wholesale seller) and here I have 100% positive feedback with 600+ stars. I don't belong to any meteorite associations or clubs because I think they create a false sense or security when considering the authenticity and provenance of meteorites.
