If you use Google to search for retailers, make sure you also search for ratings on the retailer. There are many places out there offering super low prices that are only using the price for bait. If a dealer has bad feed back or no feed back, stay away from them. No feedback indicates a shady dealer who has changed their name to avoid their bad rep. For example check out this price:
Digitals Future
Then look below at the "recommended accessories". The camera comes new with an external charger. Why should you need to buy one? Also note when you add the price of the charger, you would end up paying more than you would have from a reputable dealer (who would have left the original charger in the camera box where it belonged).
Now look at their review:

Stick with reputable dealers, such as Amazon or B&H.
