It depends. Some products automatically carry international warranties, such as Apple and Asus laptops. However, most will only carry warranties in the US.
It is the same as you going on holiday in the US/Europe and shopping The product you bring back normally do not carry an international warranty. This is no different. We are only buying the top name brand products from the most reputable suppliers, mostly from the brand itself or an authorized reseller. We just act as a go between as your personal shopper. If you do have a problem with the product we will provide support for you to help you with warranty services. There may be a slight costs for shipping but most of the time, your products will last you beyond the normal warranty period.
