Just my 2 cents, well pennies
bit OT but you can pick up 50 AA (Alkaline) batteries for around £12 ($20)
With my camera 4xAA Alkalines last for around 400 Shots, Lithium around 500, Although they are much more expensive.
I recently picked up a pack of 50xAA Alkaline Duracell Procell batteries from ebay for £12.25, Came next day
