Hi, just nipped into my local Tesco in Beeston, Nottingham and found these instore. Down from £17.50p (rrp £30) to £9.99.
All sizes and a combination of colours e.g. all grey pack of 3, all black pack of 3, all white pack of 3 or a assortment of all 3 in a pack.
Great gift for anytime in the year or just because you needs some new duds :)
£3.33 a pair...seems like a bargain to me!
