The Truth About 'Fake Discounts' During Online Sales
During festive sales, online retailers frequently boast '70% OFF' discounts. What they hide is that the base price was artificially inflated by 30% a week before the sale began. Without historical price tracking, consumers believe they are saving money while paying regular retail price.
