Nothing on their site says they are an "authorized" dealer. They are probably selling grey market and the manufacturers will not honor a warranty.
The one I looked at said there was a 'limited 1 year warranty' and did not have anywhere to see what that warranty is.
There are authorized dealers on ebay. Cameta is one and there are others.
Most of the kits or bundles sold by ebay dealers have a decent camera and lens and a bunch of junk. Shaky tripods, bags too small, cheap filters, etc.
Better off getting just a camera and lens and buying other stuff separately.
