The Empires & Allies Market

The Market gives players the option to buy and sell resources and units between you and your Friends.  To do this, all you need is a Market and some friends.  Markets are available in the Build menu as an Industry building. You can sell items through the Market by clicking your Market.  This opens a screen that shows all of the items you can sell.  Find the item you want to sell, select how much of that item you want to sell, and click Confirm. To purchase items for sale from a friend, click your friend in the Neighbors list.  Select Market to open your friend’s Market which shows you what they are selling.  Once you have finished shopping click Confirm to purchase the items you have selected. http://support.zynga.com/cp_articleview?gameId=81&Id=kA160000000GogNCAS&lang=en_US&loc=en_US
