Can you avoid the sale? - Contract Law question (lawn mower)

Someone please help!

Recently you went to an auction and bid successfully on a riding lawn mower that was worth $5000, but you were able to purchase it for $1,500. Of course you were not able to take it home that day, but did receive a receipt for your winning bid. When you got home a little later you were stunned because your spouse announced that the house was haunted, and that you were going to sell the house and that was that. You notified the auctioneer that you were not going to go through with the sale because the UCC required that sales of goods over $500 had to be in writing.

Can you avoid the sale?

What does it say in your text book? Isn't this a case example from a text book? You are able to find the answer, because you can look at the chapter. What text are you using in this class?

Maybe you will find someone who knows the answer... but you should still search that text!
