You are a cunning fellow. Thanks for showing me this sales trick. I can see that you can profit both ways in this deal. In selling this item, you profit. In return for the item, you can profit more too by selling this power supply again to somebody who thinks it is a 500watts but gets a 230watts power supply instead. You must be at least a millionaire already!
On the other hand, the buyer would have paid a total of <>RM60 in order to get only RM33 back (minus shipping cost for refund). This amount of returned money is not at all a big deal (also not worth the hassle) to a buyer like me and only you and the postal/courier service will be the beneficiaries of customer's hard earned money. While buyer like me gets a migraine, time wasting, and still no power supply.
I tell you what, my friend. I will keep what is left of this deal (cut my losses) and use this power supply that you sold me in your scheming manner to power some LED fans and help cool my "Always On" 3D rendering pc instead of having you selling it off to another poor fellow.
Will a negative feedback be useful for your shop? I have to try to inform shoppers to be cautious of falsely advertised listing like Item ID: 81378365. It is NOT a 500watts power supply when peak output is only 230-250watts! You should change the title to "ATX 230Watts 24pin Power Supply with SATA Cable" because the power supply does not even have a
peak 500watts output.
Perhaps you may want to give me a present for helping you understand, my friend. You know, like a token of appreciation for the massive inconvenience your item listing caused me and that I'm such a polite buyer. Then maybe I can consider buying anything from your shop again and tell people it was an honest technical mistake on your part in my feedback. Don't worry I will not give you a big, red negative feedback. Show me i can trust you or f*^@ o%f!
