Okay kiddo, have you ever played with building blocks? Think of a big pile of blocks like the internet. Now, imagine you want to send one block to your friend who is far away. But, there are many other people also trying to send blocks to their friends using the same pile of blocks. It can get really crowded and hard to move your block to your friend’s house.
That's what happens when lots of people try to send information (like messages, pictures or videos) over the internet all at the same time. It can create a kind of traffic jam on the internet, which slows things down and makes it harder to send things quickly and easily.
But here's where blockage discount comes in. Sometimes, if you want to send something over the internet and everyone else is trying to do the same thing, your internet company might offer you a "discount" to wait until there isn't so much traffic.
So instead of trying to send your block right away, you wait until there's not so much block traffic and it's easier to send your block. This way, your block will get to your friend faster and without any problems. That's what a blockage discount is – a way for your internet company to encourage you to wait until the internet isn't so crowded to send your information. Does that make sense to you?
