How to get a discount on student ID?

Excuse me, I was reading about the possibility of obtaining discounts with a student ID, and I was wondering if you could provide me with some more details on how to go about it? Are there specific places or online platforms where I should look for these discounts? Additionally, are there any restrictions or requirements I should be aware of before trying to claim a discount with my student ID? I'm eager to save money where I can, so any information you can provide would be greatly appreciated.
