How does she afford it?
By continuing to whore herself online, by selling her daughters privacy, by taking advantantage of anyone and anything she can to satisfy the insane greed they have, constantly seeking happiness and fulfilment that she'll never find.
By flogging any old tat without morals, constantly lying to vulnerable people to part with their money for what? So she can get sun on her bones.
By having little or low morals, she would do anything for a fiver. She's the Inchmarlo equivalent to a Dubai portapotti.
