Was hunting for a Dyson DC33 Vaccuum, when i came across the McKnights Retravision Hoppers Crossing 'Powerbuys' website. It is listing the DC33 for $445 with the RRP at $679. After doing the rounds of Harveys ($548), Good Guys ($579) and Masters ($490) i discovered this was great value.
This website appears to run as a separate business to the shop, as the shop prices don't reflect the web prices, but they said they were happy to accept the price. (They have $679 for the one on display)
They deliver across oz, starting from $9.95, or free pick up from the Retravision shop in Hoppers Crossing Vic.
Some of their other prices for things seem pretty tidy.
They also accept Paypal (Powerbuys) as payment.
