This is a trap a lot of people fall into just because it's a "good deal” doesn't mean you have saved any money buying it, It's still your own money you are wasting on stuff you probably never wanted in the first place
This might be quite obvious, but a lot of people including myself fall into this trap. The truth is that any kind of holidays or Prime Day sales, Amazon just mildly discounts their overstocked product that nobody wanted in the first place. This is not true in all instances though, you might find useful stuff for discounted price, just don't get carried away.

This is not just applicable to Amazon, but any kind of store that offers huge discounts, when buying anything just think twice, will it be truly useful to you or is it something that will go to the rubbish after a while.
