Nikon has a factory in Thailand. Do they sell their products in their factory premises?

Actually I want to buy a quality product in cheap rate. If they do so & have a good price difference, I will go with it. If you have any price idea, please share with me.

Don't bother. You're not going to get a cheap Nikon. Most of the factory workers can't even afford the things they make.

These factories area massive and do not sell to the public. The location of their factories are not secret, so you can look them up and then use google earth to get a grasp on their size.
