Purchasing decision: seemingly blister-packed single commodity

Ordered 2 batteries for each 3.72. at the unit price and prime-capable delivery I came out of their original packaging individual goods.
Well was supplied in the well-known secondary packaging in DVD-size C1, were 2 single quick release bag with label. The batteries were sealed in foil, just as they are available in large quantities. As if that were not enough, a battery was visibly depressed, let's go on the assumption that it was the transport - where is the transportation lock?

Production date is the way in both 11/2013 and are thus 7 months old, use date is specified with 06/2018 that's fine I guess.

What me now even annoyed, is that the price within 2 days, has fallen from 3.72 to 2.20. However, this does not change my vote, finally I was 2 days ago ready to purchase the item for that price.

As long as you keep in our smoke detectors to be seen. I hope so for longer than the specified by another reviewers 11 months ...
