ebay effect - You see a thing you don’t need and you think, 'I’ll just buy

You see a thing you don’t need and you think, 'I’ll just buy it,' and then you regret it for the rest of your life.

I bought a $200 pizza because it said 'gourmet.'

That $150 ‘fitness tracker’ was just a watch.

I paid $100 for a bag of chips and still haven’t eaten them.
