surcharges

A surcharge is an extra cost or fee added to a bill or price. It's like a hidden additional charge that might catch you off guard.

When shopping online or at the store, you might see a "free shipping" deal that sounds great, but then they surprise you with a surcharge for handling or packaging. Sometimes airlines will add a surcharge if you book your ticket last minute or change your flight plans. In these cases, the original price didn't include the extra fee, and it's added later as a surcharge. If someone says that their phone bill has a surcharge for data usage, they mean there's an additional charge for using more than the expected amount of internet on their phone.
