Consider the following extract from Case 10 - 6 The Shoe Seller's Case,

"The CISG expects a buyer to accept deliveries of nonconforming goods [unless they are fundamentally nonconforming] and to invoke remedies other than avoidance (such as reduction of the price and damages) as compensation for the defects. For example, there would be no fundamental breach of contract [and no right to avoid the contract] in cases where the buyer is able to use some of the goods."

Using your knowledge from Week 10 - Sales and Logistics and with reference to the case above, explain the CISG "Avoidance" provisions for both the buyer and seller.
