i understand there is a general concept that amazon and ebay are on the side of the buyers. But it depends on the situation... again even if a buyer makes a claim he has to ship the item back if he is not happy? You are acting like he makes a claim even though hes lying so he gets a refund and keeps the item... thats not how it works otherwise ebay would know hes scamming. Also, I sold an 1100$ 3DS in early October with no problems.
Doesnt this logic apply to anything, ordering from amazon corporate, bestbuy, walmart. Anyone can claim they did not get what they ordered lol but e commerce does quite fine
