Each question is hypothetical and is based in the US.

1.Tim Shaw is wandering around at Lowe's. He is looking for a chainsaw that would cut the thick and wet limbs off his 120 years-old Pine tree without much hassle. Tim asked a manager to show him a chainsaw for tough trees. The manager showed him one and said "I used this one and it worked on my Oak tree." Tim buys the chainsaw. After an hour of cutting limbs without hassle, the chainsaw stops working, and it won't start. Does Tim Shaw have any claims against Lowe's under the UCC? If so what claim(s)? Explain.

2.Lilly Little is a cashier at Walmart! Billy Ray, a good-looking guy, is about to pay for his new expensive fishing rod. Since Lilly really likes Billy's looks and manners, she gives Billy an unauthorized 50% discount on the fishing rod. A manager at Walmart finds out about this transaction and charges Billy's credit card for the discount to be paid back to Walmart. Billy decides to sue Walmart for breach of contract. Considering the principles of Agency Law, will Billy win against Walmart? Explain.
