Well I dont use amazon to buy something online because the process of their returning payment is too old school. let me compare that with flipkart well if you order something fron flipkart they deleiver as per they say but amazon takes time to deleiver the product. most of the product of amzon does not satify the customer needs.
If you return the product and want cash back then they send a person which collect the product and other person come another day to give you a cheque which you need to submit in bank. well as per flipkart their person come to collect the product and your sign on machine and they return the money same day in bank account so that you can shop again easily.
