At my local Tesco earlier I noticed that one of their tights had a two for £5 sticker on them. Asked them to price check before I bought two packs (thought the offer may have finished and the one stickered pack had slipped through the net), but the offer was even better.
The two for £5 was correct, plus is was 20% off all clothing. The 20% was taken from the pre-multibuy price.
So £6 - £1 - £1.20 = £3.80.
Good value for 10 pairs, and tbh I've found them to be very hard-wearing at the toes.
Sorry, can't find them online, so can't put a picture.
