These are priced individually at £1.22 but when I scanned 3 packs through it took off a "PamperWipe Offer" of £2.35. The total for 3 packs was therefore just £1.31!!!
Not sure what quantities this works on or if it's a misprice (not advertised in the aisle) but I went back and got 12 more packs and scanned/paid for them in threes.
This worked at Byker store, worth checking elsewhere!
