Impulse Shopping - Need help validating my MVP

Hey Hackers!

Last year, my friend had a problem with buying random things online (e.g. books, cloths, random ads). I did a little research and found out people spend $150-$200 per month impulse shopping.

We came up with an idea of creating a web extension that makes you wait 30 seconds before you can buy anything. That way, people have a chance to really decide what they want to do.

We made an MVP with a list of 200+ websites and the user can also block any other site they want.

Please check out the landing page and the extension. We'd really appreciate any feedback.
