Why would anyone shop elsewhere
The driver just phoned to advise delivery this morning between 8 and 9am.
I could be slightly prejudiced, but acknowledge the fact that the Company Award you received recently is more than well deserved for the fast and efficient way even this small purchase was handled.
I look forward to further purchases, as why would anyone shop elsewhere - even when living as far from the city as I do, to have my microwave delivered to its resting place - not to mention also the removal of my old one. Noelene, Blackheath, NSW
Best prices around and fantastic customer service.
Just wanted to add my feedback and thanks – I purchased a Fisher and Paykel washing machine and a Delonghi Dehumidifier - Best prices around and fantastic customer service. They gave me a call in the morning to let me know they’d be there between 1100 and 1300, they were at my door at 1105 and the guys were fantastic - super friendly and they had my machine unpacked and setup/tested in minutes – couldn’t be happier with my purchase and I definitely recommend Appliances online to anyone. Massive Thanks again to Tony and his mate – Great work guys. Bill, Canterbury, VIC
I am utterly impressed
Hi Joshua,
That is just fantastic. Honestly that is such a nice thing for you to do.
In October I will need a BBQ and a microwave of which I will be getting both from you.
On another note, I would just like to say how fantastic you are to deal with, who ever knew that purchasing something on line would have such an amazing personal customer service offering attached. I am utterly impressed and have been telling everyone about this sensational service.
Thank you again. I can't wait to get my new fridge.
Cheers Amanda, Collingwood, VIC
