This one drives me nuts too. Last year I bought a custom made titanium bike from a local builder that I wanted to support because he does great work. I follow him on social media and whatnot too. When I called to put the order in, he said the online prices were $500 low because their titanium vendor recently increased their prices. In other words, he had to increase his prices.

Within a couple of weeks he shared a story stating how greedy businesses are for price gouging. I really wanted to comment on it but still had to go through the bike build and didn't feel like getting into it. I can't fathom the cognitive dissonance.

This is nuanced. The reason why inflation is measured across a multitude of goods is because it aims to measure a general price increase. A supply/demand shock in a single industry ought not influence inflation too heavily. This is one of the reasons why oil is often excluded in inflation measurements - it is so heavily influenced by OPEC it makes it difficult to use as a broader indicator.
