ATR sports was founded in the year 2008, which is more concerned on the selling of jerseys, footwares etc. This platform is not difficult To navigate through, everything is made easy for better experience. The payment method it has brought up is very convenient by me. If you can pay using PayPal or Visa am sure you should be comfortable using mastercard. With this I don't think the company has problem with the payment system. Though delivery of goods is only possible in some region like the United States and Canada. Also the means of shipping is very efficient and safe. Also talking on the return policy, it is what customers have to Appreciate, the company allows for 30days return policy. And Aslo have a different alternatives for communication.
