1a Ware - Top price / performance ratio, despite plastic bag

Duracell Photo Battery CR2 (CR17355) 3.0V in 2 (Platstiktüten-) Pack, but still 1a goods.
I can not understand the here 1 * deploy, because the batteries are not sealed in the original box come the people.
The expiration date is also on the batteries and who does not believe that the are full, can indeed measure it.

My two batteries will last until March 2020 and have full voltage.

Since you can even hope that the Duracell (Easter) bunny also 2020 runs.
Compared to retail prices (9 / piece in MM) are the really given here.
