Not the cheapest ever but might be useful for some, especially with winter approaching.
A bit extra back with CR https://www.cashrewards.com.au/repco til 23May.
E.g.
CTEK Battery Charger 12V 5Amp with Bonus Powerbank & Accessories - MXS5.0PB $118.30 ($94.64 after cashback)
I just bought the 5 Amp on Saturday with their 25% off sale :(
Thanks Mod but I'm seeing $127.40 for the example you added
