The costa americano packs are very rarely on offer (even when all of the other tassimo tabs are on offer), so this is a good price. They are also £4 in Tesco at the moment, so if you like these ones, then it is worth stocking up.
Or 3 packs for £10 at Asda..
This is 16 so actually works out cheaper??! £3.99 ÷ 16 = 25p each £6.98 ÷ 24 = 29p each
seems normal price
