Why does the Apple Store online let you choose (for a PowerMac G5, which is all I tested) both "Bluetooth Module" ($50) and "Bluetooth Module + Apple Wireless Keyboard and Mouse - (language)" ($99)? Surely it's redundant to choose both, since if you choose the second option you don't need the first. If you choose both, $149 is added to your total (which shouldn't be the case due to the above redundancy issue).
