When someone says “that’s affordable” they are saying that’s a price they would be willing to pay.
A better version of the same item could cost much more and to a person with a different budget or sense of value that would be affordable to them.
So, I wonder why when the first person sees something that they feel is expensive they are repulsed, as in ‘who do they think they are charging that much for that”.
Remember, affordability is relative.
