Duracell Quantum vs. Kirkland Signature Batteries
Name-brand price: $1.14 each
Generic price: 28 cents each
The better deal: Kirkland Signature
In a Consumer Reports test of AA batteries, Duracell Quantum rivaled lithium batteries for reliability and cost only half as much. Kirkland Signature batteries made the list as the best buy of any of the batteries at just 28 cents each, which is why it’s one of the top Kirkland items only Costco insiders love.
If you don’t plan to drop loads of money in Costco’s warehouse store, you might be better off buying the Duracell Quantum batteries, however. A membership to Costco costs $60 annually, and the generic brand batteries are only available in two 72-packs for $39.99.
