Yesterday I purchased 5 packs from Waterguy3434 on eBay at the "Buy it now price" of ~USD100 each.
If I purchase in Australia it would be AUD369 each at Justtools. http://www.justtools.com.au/prod3798.htm
The current exchange rate is 1 USD = 1.1330 AUD
The price sucks here in Australia.
I bought a pack from this guy a couple of months ago for testing.
Not sure but I think he buys DeWalt combo packs and sells the individual pieces separately.
Pack arrived undamaged and in excellant condition. Each cell 3.30V
Thanks Doc but I only needed 5.
