CASH CRUSADERS. EISH

GOOD DAY. I FEEL VERY CONFUSED AFTER TRYING TO PURCHASE AN XBOX 360 REMOTE FROM CASH CRUSADERS IN HERM****. HENCE IT WAS AN 2ND HAND ONE AND PLEASE NOTE THERE WAS TO ON DISPLAY. WHY THIS CONFUSED ME IS THAT THE REMOTE TAKES A BATTERY PACK, THESE REMOTES DIDNT HAVE. SO I WALK IN THERE WITH HALF AN REMOTE THEY WOULD BUY IT FROM ME LIKE THAT? DONT THINK SO. MY ARGUMENT WAS WHY WOULD THEY BUY AND SELL IT THIS WAY? THEY CAN AND OFFERED ME ACCESSORY ON THEIR SHELF. MEANING I HAVE TO PUT MORE MONEY IN FOR OVER PRICED ACCESSORY. MANAGER STATED THAT THEY BUY LAPTOPS WITH OUT CHARGERS BUT WILL THEY BUY A LAPTOP WITH OUT A BATTERY BACK?? POOR POOR POOR.
