Ever notice how a 'Buy One, Get One Free' deal magically makes you grab two when you only needed one? Supermarkets are pros at using sales to make us buy more—think flash sales that make you rush, or those 'buy 4 for $10' offers that fill your cart. The real trick? These promos tap into our FOMO and love for a bargain, making us spend more than planned. Next time you see a killer deal, ask yourself: do I really need it, or is the sale working its magic? #SmartShopping #SupermarketHacks #MoneyLifehacks
