> A rationale for the price rarely affects my choice.

This would make you the exception. Companies are constantly increasing prices to see how much they can charge consumers before they feel cheated and stop buying and/or enough customers get priced out to hurt profits.

Consumers tend to feel ripped off if they think a price increase was due to greed but are way more forgiving if they think the price increase was needed because of something outside of a company's control. That's why companies are quick to tell consumers that rising prices are due to things like fuel prices, bird flu, or supply chain problems.

Of course, that tactic isn't as effective as it used to be since consumers have seen companies using those excuses and feed them lines like "We're all in this together!" while those same companies report skyrocketing profits and they've watched as prices remained high or even increased even after the blamed fuel prices dropped and supply chain issues resolved.
