If you're promoting your affiliate marketing products of any company, it's meant to be focused on where customers can access them to buy. If you promote a product where it can't be reached or delivered, it's a wasted effort in your affiliate marketing.
Certain times, it might be ideal to market products to a group of certain people who may be residing in certain countries. This is quite important, especially when the demand and supply of a product is country-specific. Walmart is not available around the world and they have specific customers living in specific countries.
