Shrinking shampoo bottles (again)

Unilever's Alberto Balsam have brought out "new" 300ml bottles of shampoo that Tesco sell for almost the same price (£1) as the previous 350ml bottles, so you now pay the same price for less. They did the same thing 9 years ago so Unilever's commitment to reducing plastic use is a farce because the product now comes with just 60% of the shampoo it originally had.
