I bought a lot of my electrical appliances (aircon, washing machine, dryer, hob, hood) from Parisilk. They were willing to match prices if I found any lower ones. I walked around Courts and Best Denki to identify the brand/model/prices of the appliances that I wanted and sent them an email directly to ask for a quote. Turned out they were indeed much cheaper than the big chains.
Although after I placed my order, I found the same model washing machine being sold for $50 cheaper at Mustafa.
So I would suggest that you take a look at Mustafa and Parisilk and compare prices.
