It is well known how useful it is to have a second battery for your DSLR camera. Besides it is advisable to use original brand equipment, specially when it comes to batteries. So, I'm currentley looking for a new and original Nikon battery for my D3300 (the battery is an EN-EL14a 7.2V) but it has been impossible to find one! First I found one in Amazon but some of people commented that the battery wasn't original in spite of the price. So I looked for it on the Nikon USA page, where they recommend some stores (in Miami in my case). In the only one among the ones they recommend where I could find the battery that works for me, was Best Buy but as far as I know that's not a trust worthy place when it comes to warranties (as you can tell by the comments in here).
So what I came to ask you guys today is: Is there any place in which I can buy a original Nikon battery safeley? Have any of you have had troubles like this before?
Thank you all in advance
