Where do you guys buy CR2025/CR2032 button cells? Is there some nifty online source with reliable quality and discounts for 10 packs etc (TradeMe - ha ha haaaa...) that I don't know about -- or should I just stick to 1 and 2 packs of Panasonics from Mitre 10?

I know I mocked the reliability of TradeMe traders, but I do admit to buying button cells from DX before (which is where it seems a lot of TradeMe traders source all of their stock!). And DX are very cheap, e.g. 5 cells for US$2 - but I suspect the 'genuine Sony' and Camelion branded cells are not quite as authentic as they seem ;-) . And due to airline regs DX will no longer ship lithium cells to NZ anyway... not that I'm even sure some of these are genuinely even lithium.

Cheers.
