Found these today at Jarrow Home Bargains. Having 3 sons I'm always on the lookout for deals on undies and this is a great price. Peeled the stickers off the packaging and it seems they were originally from TU clothing (Sainsbury's I think) and that the original selling price at TU was £9 (size 7-8) or £8 (size 5-6). Can't see on-line so seems they are only in-store. Sorry about the rubbish pic my phone's not great!
