Nothing more fun than the battery shelves at Jaycar, with their endless variants of CRxxxx batteries and no apparent sort order. :)
I know that Woolies (probably not the city store if the Coles city store is anything to go by - caters mainly for the 'on the go' employee) sells both 2032 and 2016 but I've not looked for 2025 before.
Jaycar and Dickies should both have them, unless Dickies folds before lunch.
Can I use a gift voucher?
