Stumbled across an Australian website called 'CrazyStu.com.au' that are selling Eneloop batteries and chargers at low prices, so I thought I would share.
Below is the banner from their main page showing the different packs and prices
Shipping is $5.95 but overall is still the cheapest I've seen (correct me if I'm mistaken!)
I've just ordered the charger and 4xAA pack for $16.50
