I am currently using RepoMarket and have bought a couple of repositories from there. There is a dispute option which is very great incase the repository is not up the par. All in all great platform with many benefits to developers and buyers.
Repomarket is a well made tool that allows me to showcase my work and aim to get paid by it. I look forward to being more involved in the community that forms within it.
The company has great potential, this is a superb concept and gives developers a great potential in making some money by placing their ideas on the market.
