Woolite 1 litre size bottle that washes 16 loads of washing for just £1 (usually £2.99 or more). They had the colour version and dark (for mixed dark loads) version in my store.
Also comes with the plastic ball on the top for use in the machine. Just put a cap in the ball and youre away.
Ive been buying the small n mighty recently as i like to work on a 10p a wash figure. This has been on offer at £2 for a 21 wash pack so works out at just slightly under 10p a load.
This Woolite though at a £1 a bottle works out at just over 6p a load. Bargain!!! Stock up.
Lady said she only noticed they got it in today.
