Persil have shrinkflated their liquid detergent products from {25,40,60} washes down to {24,38,57} washes. Their website hasn't been updated yet but the new products have appeared on Tesco's website.
They haven't reduced the size of a wash (it's still 35ml) but the initial price for 38 washes is £8.00 whereas 40 washes only costs £7.00. At over £6 per litre this is significantly more expensive than the usual special offer prices of £3.33 to £3.57 per litre.
