Hi I am Suman Saha customer of Amazon from 2014. In these 4 years I already bought 300+ product. In 2016 I became amazon prime member. After prime membership all products shipped to me through amazon transport service. I noticed that when I ordered a big value product it shipped to me very fast through amazon transport service but if the product value is less then the product shipped lately. This is observed by me. Please input your opinions regarding this. I also talk with the transporters or service men who doing job in amazon transport service. As per them company s other things is good.
