Extended Warranties: Often sold for electronics and appliances, extended warranties rarely pay off.
Brand Name Prescription Drugs: When generic versions are available, brand name drugs can be a significant rip-off.
Convenience Fees for Electronic Payments: Charging extra for paying with a credit card online or through other electronic means, especially for services like utilities, tickets, or taxes, can feel like a needless penalty for convenience.
Designer Eyewear: The markup on designer frames can be astronomical compared to the cost of production. Much of the cost is for the brand name, not the quality or functionality of the glasses.
Bottled Water: In many places, tap water is safe, clean, and practically free. Yet, many people buy bottled water, which can cost thousands of times more per gallon than tap water.
Gym Memberships: Many people pay for expensive memberships they seldom use. The cost per visit can become exorbitant if the gym is underutilized, making it a poor investment.
Ink Cartridges for Printers: Printer ink is famously expensive, often making it cheaper to buy a new printer than to replace the ink. The cost per ounce of printer ink is higher than that of luxury items like champagne or perfume.
Pre-Cut or Pre-Packaged Fruits and Vegetables: Convenience comes at a high cost here, with pre-cut produce often being much more expensive than whole fruits and vegetables, despite offering the same nutritional value.
Hotel Room Service and Mini Bars: The markups on these conveniences can be exorbitant, with items often priced multiple times higher than their retail or restaurant counterparts.
Textbooks: New editions of textbooks can be incredibly expensive, with only minor updates from previous versions. The resale value drops dramatically, making them a poor investment for students.
