Does doorstep delivered, glass bottled milk taste better than plastic bottled milk???

I’m on about glass bottled Dairy Crest milk, delivered to your doorstep.

Does it taste “significantly” better than plastic bottled, supermarket milk?

Do you know how much it would cost to get 1 pint of semi-skimmed milk delivered 3-times a week?

Is it worth the extra cost, if it is more than supermarket milk??
