I am about to buy a new fridge and asked Harvey Norman to price match a competitor.
They would not price match because it was not a 'like for like' product. Harvey Norman currently offers a bottle of wine with electrical purchases over $399 and the competitor does not.
Once the promo is finished at the end of the month, the price goes up $200. But there most likely will still be plenty of competitors with prices at the current level.
I don't want the bottle of wine, just the cheapest price. Are they within the policy to do this or are they bending their own rules so they don't have to price match?
This applies to all electrical items over $399.
I suggest you stop worrying about this and try bargaining at a different store. Or better, try the other stores like TGG, Jb HiFi, etc.
How stores interpret policies is entirely up-to the salesperson you are dealing with at the time.
