On November 1, Sleazy Sally l sent a letter through regular mail to Big Bubba. The letter stated the following: "Big Bubba, I'm offering to sell you my manure spreader for $1000. It runs good. Please let me know if you want to accept my offer." Big Bubba received the letter on November 2. Big Bubba wrote a letter back to Sleazy Sally with the following text: "The price for your manure spreader seems too high. Would you consider $800?" Big Bubba deposited that letter into a nearby mailbox on November 3. Sleazy Sally received the letter on November 4, at around 4 p.m. Coincidentally, Sleazy Sally had had second thoughts about offering to sell her manure spreader, and she sent Big Bubba a revocation of her offer. She put the revocation letter into a nearby mailbox at around 10 a.m. on November 4. Big Bubba received that revocation on November 6. On November 5, Big Bubba decided that he wanted to buy the manure spreader for $1000. He put a letter to Sleazy Sally in his nearby mailbox on November 5 with the following text: "I am jiggy with your offer." Unfortunately, Big Bubba, who sometimes has problems spelling words, misspelled the name of the street where Sleazy Sally lives. Due to this error, she did not receive his November 5 letter until November 10. Is there a contract between Sleazy Sally and Big Bubba? Why or why not?
