I was at the big Primark store in Oxford Street, London, today. They had towel sets on offer for £2 (were £5 before). These sets contained 2 big bath towels, 2 hand towels and 2 facecloths. Great price if you're looking for some extra towels. There were cream sets and mixed pink and white sets.
They were stocking the items all the time, on the ground floor and also on the second floor. So, hopefully plenty left for people who want to buy the set.
