Where to buy dp2m extra batteries?

Ehh...

I figure even if the charger dies it's still amazing value.

I contacted Blue Nook and they replied quickly and said they'd do whatever I like to make it right. For some items I'd just return everything and go the OEM route. For this though, I'm just gonna let them replace the faulty battery and carry one. We're talking 3 batteries and a charger for less than the cost of one Sigma or even Ricoh battery. I don't really care that much if they don't hold up over the long haul at that cost it's still smart shopping. If the Sigma camera battery performance we're such an issue I'd just cough up the money for an extra official battery, but when you need at  the very least 2 extra, it's a different story.
