I give up buying any new toiletries during Lent, which helps makes me use up the collection of half used bottles of shampoo and shower gel etc cluttering my bathroom. Anything I really don't like by the end of Lent gets given away or disposed off, as part of the subsequent Spring clean, and I make a small donation based on the amount I' estimate I' ve not spent on toiletries to a favourite cause. If I feel I have been really successful, I then treat myself to a new bottle of my favourite but very expensive shampoo.
