Question about Oehlbach Banana B3

I had 4 plugs in 1 pack at the time (in 2018).

In order to be able to connect my two speakers to the receiver, I had to order 2 packs of 4 at a time. In 01.2017, they still cost 22 Fr. per pack, making a total of 44 Fr. The picture of the product shows that it has 4 banana plugs in the package! This is also stated in the product description.

1 (One) piece cost Fr. 28.50 in March 2020, all four thus Fr. 114.-
