Buy the electric appliance

You can go to 教協 Causeway Bay to buy it.
Some electric things e.g. Air conditioner, washing machine......
They are more cheaper than Fortress, Boardway.....They are all from main dealer.
You can check the price on there.
But you need to have membership card. If you do not have card, you can borrow from your friend who is teacher. You can also pay by Diners card. I always buy so many thing there and borrow the card from my friend and save a lot of money.
