First post, so please be gentle :)
Dettol Disinfectant Lavender and orange oil fragrance 500ml only £1 in PoundLand.
Really nice fragrance, can be used to clean many surfaces, in laundry and as skin cleanser (when diluted).
Normally £1.95 in supermarkets, Tesco own brand equivalent 95p, ASDA own brand equivalent 55p. But I found Dettol quality is much better.
There are other Dettol products, all £1. http://www.poundland.co.uk/brands/dettol/
