Recently I learned about your site and it is quite impressive. Thanks for your wonderful work. I do find some problems that can be improved so that you can achieve better results. For example, there are many repeated products and some contains errors. Why not allowing viewers to report mistakes on webpage? It is not hard to report, just replace one of the buttons " into "reporting error". And when more errors are found, you may delete a webpage. That's my simple suggestion and I wish you greater success.
