Why does a bottle of Coke cost pounds whereas an own brand cost 15p a
litre. Quality or just the customer paying for all the advertising?

Some of both. Mostly the former.

Where is the quality in a bottle of flavored carbonated sugar water?

I think you've been caught by the same advertising that results in the
poor in developing countries buying Coca Cola rather than food because
they see it as westernised and therefore better for them.
