THAT is the influence of marketing, media advisers, etc.
Meh, I don't really feel like that's true. We don't have any of those people in our organization, but the majority of people expect a justification for a price increase.
I would imagine there would be more posts in here for getting a letter from their service provider with a 10% price increase if it didn't contain anything.
Dear Consumer.
We have made the decision to increase your prices 10%.
Regards
Provider.
