Normally I avoid HN like the plague unless price matching but I think this is a decent deal. Harvey Norman are selling the Westinghouse 420L Top Mount Fridge (WTM4200WBR) for $839 with a bonus $90 eftpos card.
The effective price becomes $749 + $49 delivery = $798 delivered. Free in-store pickup is also an option.
We bought the exact same fridge over the weekend at another retailer for $810 + $45 delivery which was the best price we could find on the day. (Harvey Norman's price was $999 with no eftpos card and they would only match the Good Guys price of $817 + $45 delivery).
Australian made fridge with 2.5 star energy rating. Note that the eftpos cash card redemption looks to be with HN themselves (not the manufacturer) and seems to only apply to the Right Hinge model. I'm not sure if you could buy the Left Hinge model and still be eligible, might be worth going in-store and showing them the url to see what they say.
maybe this is why?
