Scrolling though the Black Friday week of offers on Amazon, we have a Brita Jug, so I thought I would check to see if there was any good deals on the filters, many bought in bulk worked out around £7.00p each, then I spotted this add for a box of 15 and thought that must be a mistake at that price, looking at all the text right at the end is the word single, yes it is not a box of 15 as shown in the picture, just 1 at £9.99 an expensive way of buying them.
