This month, one customer from Slovakia has expanded his business on chips, and he is looking for 3000pcs ATMeg2560-16AU 
We started cooperation in 2017, now he entrusts us to handle all his procurement and delivery in China
Because of the epidemic, this chip is in shortage in the Chinese market
I have checked with many suppliers, and finally found one supplier with good reputaion on 1688 Platform(/www.1688.com)

The supplier send us this quotation and ensure us the product is original (we can check the products first, then release the payment)

Our customer compared the price, and thought the price is a little higher than his target price
So I have applied with the supplier for better price

We checked the product picture before the supplier send the chips to us 
After we got the chips in our warehouse, we took photoes to customer for re-checking
Our warehouse re-pack the chips carefully and shipped out after our customer confirmed the products 

I am very happy to help my customer find his target products and complete this purchase
Look forward to more cooperation in the future
