Black Friday is rapidly approaching. But even as retailers continue to hype sales for the holiday mega-deal event, global supply-chain concerns linger. Online shoppers saw over 2 billion out-of-stock messages in October alone, according to Adobe analytics. And inflation is at a 30-year high, meaning the cost of everyday goods is steadily increasing. Holiday shoppers be warned: The Black Friday sales you’ve come to expect are still happening, but they’re in more-limited product categories, at higher prices than in previous years. So it’s more important than ever for shoppers to find real bargains on items that are actually worth the money.
