I think a lot of people could save a lot of money with a browser extension that just gives you a little bit of time to think between you put something in the cart of an online store and before you're able to click trough to purchase it.
Say you click Add to cart, and the Checkout button is locked by a 30 min countdown. Wouldn't that be enough for some compulsive shoppers to forget or realize this was a bad idea?
The world needs every bit of less overconsumption it can get.
