Instructions
Wait until a date for the Flea Market has been announced. The Flea Market happens toward the end of every month and is announced one day in advance.
Visit your neighbor's house on the day of the flea market.
Talk to your neighbor. He will ask you if you want to buy anything. Select "Yes!" and begin looking around his home. When you find something you like, click on it and your neighbor will tell you whether or not it is for sale. If it is for sale, he will tell you its price and provide you with an option to accept or decline his offer. Select "I'll buy!" to purchase the item.
