On time and more than helpful
A big thank you for the great service we experienced this week in buying our new fridge which was delivered today. The purchase was very easy and the phone staff excellent. The delivery men today were outstanding and were on time and more than helpful. We will never buy another appliance from any store but your company. Thanks again Natasha, Clayfield, QLD
A company who serves people
I would like to express my thanks for your performance as a company who serves people. After 21 hours since my old washing mashine collapsed I was able to start my washing with a new 7.5kg Front Load Samsung Washing Machine WF8750LSW1. The staff was so proffesional Steve was a very helping to unswer my all questions. I said he is a great ambassador for his company. He was patient and no in a hurry. I am also very happy to choose this model of Samsung as it covers all my expectations to get great results on wash with many different cycles. Definitely I will share your address with my friends.

Great service and free delivery
Thanks Appliances Online. I ordered a fridge online on Monday and it arrived at 8am Tuesday morning. Great service and free delivery plus my old fridge was taken away free of charge and the new one installed...can't get any better than that! Thanks also to the delivery guys for their friendly, courteous and professional manner. Appliances Online Customer, Australia
