Most Aussies didn’t celebrate Thanksgiving yesterday, but that won’t stop us from shopping up a storm, as US-inspired Black Friday and Cyber Monday sales promise to be bigger than ever. Last year, we spent $6 billion in a 4-day frenzy, and despite rising interest rates, the Aussie Retailers Association expects we’ll shell out $200 million more this year. That makes them twice as big as the Boxing Day sales… And while it can be an opportunity to save money, the official watchdog warns that some retailers exaggerate how much of a bargain something is. That’s echoed by retail psychology expert Dr Melissa Norberg, who says we shouldn’t get sucked into overspending due to FOMO, buying things we don’t need, or worse still, can’t afford. So if you don’t need a 5th pair of white sneakers, maybe cool it. That’s some good self-talk right there…
