Went into Tesco today and the nappy pants (Tesco version) were on the shelf for £7.88 (I think it was £7 something) each but scanned at £4.04 per pack.
Better value for these as the smaller packs of 20/22 are £3.33 or the bigger packs are 40/42 at £4.04.
Checked online and they are advertised as £4.04 each, not sure if they will do the 2 for £11 online though but instore they definately go through as the individual price.
Picked up 2 packs.
According to the website valid until 31/12/11 so on offer for a good while yet.
