I’m currently doing a research for a uni project. I’ve been googling around, looking for sites that offers editable stock templates similar to GraphicRiver for comparison (e.g.: flyers template in PSD , resume layouts in INDD , even presentation files in PPT ). Strangely I don’t find many of them. The only result that relevant as a comparison to GraphicRiver is 
Sites like  or  do sell business card or flyer templates as well, but they fall under Vectors category, not dedicated Business Card or Flyer category like in GraphicRiver. The rest that I found are mostly stock photography or stock footage sites.
Is Graphicriver one of a kind for such files? Do you guys know any other sites that I probably miss?
