Amazon amazing service

I bought a golf watch from Amazon out of the USA . I am very impressed with the service ;I was constantly advised the whereabouts of my purchase , no hidden costs ,my package arrived 1 day earlier than expected and exactly what I ordered . The watch was couriered to me by DHL express which themselves are very efficient.( No Post Office surly people ,queues and missing items) 2 weeks later I get a refund of USD 1.97 because the import tax that was payable in South Africa was lower than estimated by Amazon
