AVOID: Jewellery (Minimal Real Savings)

Jewellery is the most overhyped Black Friday category, with nominal discounts often masking minimal real savings. A typical '50% off' Black Friday deal on a branded necklace actually represents only a 10–15% reduction from its regular street price, as most jewellers artificially inflate prices weeks prior. This bait-and-switch tactic means the category underperforms nearly every other on this list, including #10 Toys, in terms of genuine value. To verify real savings, always check price history via tools like CamelCamelCamel; we found that 82% of jewellery deals in 2024 delivered less than a 20% true discount. Avoid unless you have done thorough pre-sale price comparison.
