Marked cards, buy or not?

Many customers are very forthright when buying the products. Usually these are our regular customers. 

However, some customers have some doubt when need to make the payment. Let me just analyze it in the following points. 

1st, Why is this products so expensive? It all depends on the quality of the products like marked cards and infrared marked cards. Usually you get what you pay. But sometimes we don’t want to sell products with not so good quality. 

2nd, why the customers need to pay the shipping fee? For this point, we are in China and you are welcomed to our office to see or buy the products. In this way, you don’t need to pay any shipping fee at all. But if you need us to send the products to your place, you need to pay the fee for it of course. 

And what’s more, it may take some tax for the Custom sometimes.
