I haven't done any webscraping on ozbargain to confirm this, but it feels like there have been fewer and fewer JB Hi-Fi deals over the years.
In fact, the only popular ones I've seen recently are the "sign up with Telstra and get a free gift card" deal. Maybe the good guys acquisition had something to do with it. Furthermore, now you can't even track prices uses PriceHipster anymore.
I generally find JB Hi-Fi kind of overpriced anyway, compared to other places (online, eg. eBay or AliExpress/Banggood). Fun to have a browse through if there's a physical shopfront, but I never actually buy anything from them.
