I answer to your question:
1. The order is placed by Mr. Cao. Unit Price is based on the purchase price of delency company
2. I think the purchasing department should ask the supplier to sign the principle contract and a quotation of items that the company will buy regularly, the unit price will be used for 1 year if any changes in the vendor price should make the notice and it is received by the two parties. The buyer relies and that checks and is responsible for the price.
