It's not easy to find your way around: https://www.digitec.ch/fr/s1/product/panasonic-eneloop-pro-4-pcs-aa-2500-mah-batteries-piles-5691944 Panasonic eneloop pro / 4 pcs, AA, 2500 mAh for chf. 18.10 https://www.digitec.ch/fr/s1/product/panasonic-eneloop-pro-hr06-box-mignon-4-pcs-aa-2500-mah-batteries-piles-10265239?supplier=8902998 Panasonic eneloop pro HR06 Box Mignon / 4 pcs, AA, 2500 mAh for chf 31.75 The characteristics of the batteries are the same in the 2 articles, but the second article includes a very small box whose price is thus the difference between the 2 articles, that is to say chf 13.65. That's a lot of money for any piece of plastic. Am I missing something?
