I am regular customer of Amazon since 2014. Purchase many products like mobiles, accessories, home product etc. The best thing is that Amazon have easy return and refund potion for those who not satisfy with product.
The Amazon return whole money or replace product by another one.The amount directors neft at bank account if produce fulfilled by Amazon. I purchase my first Lenovo mobile from here and no any issues were made during 7 month of use this mobile. So this things show that Amazon is best shopping sites ever.
