As I expected, the seller makes up for postage (about 7, for an expedition of £ 1.5 from Great Britain). But ultimately, the total cost is less than 8 to 10 batteries, which puts it within .80 piece, which is an excellent price for functional batteries until 2019.
Would recommend, so if you make a significant consumption of these batteries, or a bulk purchase with friends ... Attention to properly assess the needs, this kind of battery is supposed to take 5 to 10 years in normal use ... Also think of throwing them in a place that gets the batteries, as they are toxic, like all batteries ...
