Based on BBB reviews and my own experience they list cameras on the site at hundreds lower, customers order the camera.
Then they email you and say you ordered the international version (nothing on the site suggests that) that doesn't have the same features and "won't work". You can upgrade to the domestic version for $300 ($100 higher than other stores).
This is what happened to me, I told them to cancel the order, he said there would be a 5% charge. I told him I would refute the charge.
In the end no charge was made at all - so they are just wasting time and trying to make money by scamming and lying to people without being flagged by banks etc.
Avoid the headaches and don't support these people.
