Received an email on March 12th at work: Hi G, Payment for 10mm linear bearingdone, please check; Kind regards ,Z

After I checked the account, it was true; the paypal address was exactly the same as the customer gave;

I also replied simply and added her Skype; the customer passed the next day, I didn't have too much contact; occasionally say hello; after the third day, I found that the customer received a sample of 10mm linear bearing; contact her online Hi Z,how are you? I find you had got the 10mm linear bearing ,everything ok there? The 10mm linear bearing is in good condition?

She also replied that everything was fine. After a few days, she gave me feedback that the 10mm linear bearing is already in use. In normal work, she is preparing another 10mm linear bearing order. I am very calm and know that the customer will not There is an order with too much 10mm linear bearing, but I still contact the customer as usual, simply say hello;Share some daily routines; after 1 week (end of March), the customer sent another email;Hi G, Thank you for your help, The bearing works fine;And i need these items, please quote me; Kind regards,Z

In addition to the 10mm linear bearing, there are more than a dozen models quoted, I am more serious than last time; the reply is more comprehensive, each model is marked with the brand, date, what goods, delivery time, etc.; Reported more than 2,000 US dollars; due to paypal fee, I recommend customers to use T / T; customers also agreed, but the handling fee does not agree (we charge 40 dollars each); she said to pay all the fees there, We will receive the full amount. I also agree; one hit;

A few emails have been fixed, customers pay, we ship on time; in this way, customers keep orders of 3-5k US dollars per month

If you need any brand bearings or any models of bearings, please contact me!
