I was just doing a random search for JB HiFI Commercial as there was an old OzBargain post mentioning that things could be cheaper there, but then they added a password to limit entry/use.
However, I found this link: http://mbabenefits.com.au/racgp/
That takes one to the JB HiFi Commercial portal for RACGP and when clicking on the bottom then takes you to JB HiFi Commercial.
Haven't tried it yet or compared prices, but thought I would share in the forums.
Have used this system quite a bit. Price is usually between 5 - 15% cheaper than regular ticketed price on most items. Sometimes you do get quite a large percentage mark down on some items (e.g. XCD 3D VR 3D Headset at $20.89 instead of $29.95, which equals to around $30% off, see https://www.jbcommercial.com.au/familyandfriends/product/XCD…). However, for some other items, there are hardly discounts at all (e.g. Soniq TVs) and sometimes they may even be more expensive than usual ticketed price. Also, you lose out on any promotion deals and it usually take around 2 days for them to process the orders.
