please answer C2(c). Thank you(Negotiation hardball tactics)

Question C2 Bill is the sales director of a large Pharmaceutical Group mainly manufacturing and selling hygiene and cleansing products in Asian cities. Due to the globally widespread coronavirus, face mask, eye protector, hand sanitizer, gloves, etc. are in heavy demand and thus many new production plants have joined the business and the product prices have become negotiable. Pauline is the purchasing manager of a major Cleaning Company in Hong Kong which has cleaning services contracts with a large number of private and public housing estates. Thus, Pauline needs to buy a huge quantity of protective products to keep frontline employees clean and hygiene. At present, what Pauline needs the most are face mask and hand sanitizer. After checking the prices and stocks of two suppliers, Pauline has invited Bill to her office to talk about the big purchase. The two suppliers quote face mask at $1,500 and $2,000 per thousand, and hand sanitizer at $800 and $900 per litre respectively. However, Pauline finds the prices are a little high based on the information she collected from her professional friends. Before the business meeting, Pauline has done good preparation for satisfactory negotiation results. Pauline wants to provide frontline employees with enough working materials to keep them healthy and virus-free for praises by her boss and colleagues. She has prepared to ask for a minimum discount of 8% and an ideal figure of 12% for both products. During the meeting, Bill emphasized that face mask is still under heavy demand in the market. He said, I can only offer you a discount of 5% for the face mask. But for the hand sanitizer, I can offer you a discount of 8%. This is really a special offer which is very reasonable! Since face mask is more important, Pauline negotiates this item first and promise to buy a lot more if Bill accepted 10% discount. After quite some time, they fail to agree on the face mask and Bill suggests discussing hand sanitizer first. They thus move to it and finally agree at 10% discount. When they come back to face mask, Bill said it is highly difficult to offer 10% discount. As Pauline is referred by his good friend, Bill wants to make long-term business. Bill stresses that he would try his best to get his boss's permission for a good discount. After 10 minutes, Bill returns and claims that 8% is the best offer his boss would accept. This is the best he could really do for her. (a) How could Pauline improve her BATNA, and what is the main use of BATNA in negotiation?
