I've had so many bad experiences with convenience store payments that I'll unilaterally cancel or report the transaction. (It would be great if we could just have normal transactions... lol) Regarding "price reduction requests," I've never seen anyone actually buy after a price reduction, so I only have negative experiences. Therefore, I don't lower prices. I just want to have smooth transactions, but I've had so many unpleasant experiences. I think price negotiations are a foolish question, as sellers are usually already offering prices that are barely profitable. For some reason, even if I reluctantly lower the price, I get comments like, "Why didn't you just set that price from the start?" or "How much were you trying to profit?" which makes both parties feel bad. The level of civility is too low. I've reported so many people... lol...
