Samsung has it's own etiquette that every franchise or reseller of their products has to abide by. It's quite an ugly way of doing business since it limits basically every store, but there is not much they can do other than to follow what Samsung think is good or bad. If you think Samsung is bad, then try to sell Apple stuff, it's insanely difficult and barely profitable. I remember a local Apple reseller here having said that they only make around 5% per sold item due to Apple's firm price policy. It's impossible to even list their items at discount prices, even when it concerns older generation hardware and things like USB cables and chargers, cases, etc.
