Do not get confused, or create confusion for others:

Not only the situation you're showing is NOT price gouging -- it's the opposite of price gouging.

You found one shop that sells at a price, and another one that sells at another price. You are able to choose which one you prefer, because there is plenty of inventory and no one is forcing you or any other customer to buy at the more expensive price. Each store has a different strategy, including what margins they have for each item and which ones are loss leaders, hooks, etc. You can't even know if the expensive store is making any money at all just because their prices are higher. Such direct relationship just doesn't exist.

This is a perfectly normal situation that has nothing to do with the obvious and undeniable price inflation that the whole world is experiencing, which is a direct consequence of the monetary policies of central banks and irresponsible governments.
