Co-op have some good deals on currently. One of them is massive boxes of Daz powder at £5.50 for 80 washes. That's less than 6.9p per wash. Definitely one to get you "only under 10p a wash or its not a deal" excited. Tesco have sold it for £16.34 previously and it's currently £12.99 in B&M. Think it's only the larger stores stocking so you wont find it in their smaller stores. Also have Plenty 8 roll for £4, Pampers Wipes 12x54packs for £10 and 16 piece dinner sets for a tenner also.
