three-for-one

Bought some fresh "Nexxtech" 2032 lithium cells for my portable weather station from neighbourhood The Source. $4.99 ea.

This time they offered me a "two replacements" extended warranty (for $1.49 ea.)! Yep. Now I will be able to replace, for free, each battery two more times, within the next 3 years.

That effectively drives the price per battery down to $2.16.

Again, this is a great deal, with the Oregon Scientific eb313hg weather station that goes through these batteries like lunch.
