I recently made a purchase from a site where it looked like I was getting a great deal. However, the product I ended up getting was not what was advertised at all. (I know, I should have been more cautious in the first place)
But would it be possible to allow us to flag a merchant in the app for this kind of thing. Perhaps if a merchant gets flagged a certain number of times (on unique transactions), payments to that merchant could be blocked with a message explaining why?
