Cool, you mean like your own AliExpress? Would love to get a broader range of suppliers and not have to sift through so many fake product ranges and products covered in chinese/asian writing.
Blind drop-shipping doesn't mean much when you're dealing in English and your products and instructions are covered in Asian text or not much better, pidgeon English that's full of spelling and grammar errors.
PS. I also came here looking for how to change main image. Also I just noticed this post is already a year old so I guess the supplier database never happened.
