Harvey Norman Business price check for Bissell CrossWave Cordless Max

I was wondering if someone with a Harvey Norman Business login could please check the price for a Bissell CrossWave Cordless Max? The sales offer me $540, I want to check is there any better price.
TGG Commercial price is $469 but it is a different model. The one from Harvey Norman comes with one extra roll and one extra year of warranty.

Thanks for any help

And BTW how can I get Harvey Norman Business and also for the AMEX offer can I use it on Harvey Norman Business or it is Harvey Norman only?
