Duracell 40-Pack Batteries — Pay $18.99 at Costco (Only $0.47 per Battery)

Duracell’s 40-count battery pack is on sale for $18.99, down from $20.99. That’s just $0.47 per battery.

We saw this deal back in October 2025 when it was $1 cheaper. If you go through batteries often, this is good savings compared to Amazon, where a smaller 20-pack sells for $16.05, or about $0.80 per battery.
