Hidden fees are not necessarily hidden in the sense that they are secret. They are usually listed in contracts or invoices but are easy to overlook or misunderstand.
These fees often appear as adjustments added after the base shipping rate. Because they are applied in different ways, they can be difficult to track without a detailed breakdown.
Common examples include:
- Fuel surcharges
- Residential delivery fees
- Delivery area surcharges
- Address correction charges
- Peak season adjustments
Individually, these may seem small. Together, they can significantly increase the total cost per shipment.
