• The different colors for the USB ports denote the type of USB port it is: Yellow: Power port Blue: USB 3.0 that is backward compatible to earlier versions (2.0 and 1.0) Black: USB 2.0 With regard to the pricing issue. You should contact your Best Buy Store immediately, before the ad ends, produce your receipt.
