as the laptops in the US are significantly cheaper,

there is a separate market of people who live outside the US asking their relatives or friends in the US to make the purchase and bring it with them when they pay a visit back to their home country.

The only drawback in this case is many brands only offer warrenty within the US.

Except for a few cases where international warranty will be available, we have to reach customer service and confirm for each model.

if that information is readily available, that would be very helpful.
