what do you mean by that?
I mean there is such as thing as "buyer's remorse".
Most people are somewhat vulnerable to it. Some more than others. Don't know about you at all.
Nearly everybody is sensitive to price to some extent. Don't know about you at all.
What would cause you to regret your choice? How big a deal would that be?
What might cause you to lean toward buying cooler A rather than cooler B?
Reviews? Anecdotes from strangers on the Internet? The last 10 dollars in price? We don't know.
Maybe you would spend 50 dollars more if you thought it would reduce the possibility of regret. Maybe only 10 dollars. Maybe nothing.
In the final analysis, it is highly personal and involves some degree of luck and guesswork. You could be happy or unhappy with any choice.
