Iowans who like to shop at stores where everything’s a dollar may soon see some changes. The Dollar Tree chain is buying rival Family Dollar for $8.5 billion. There are about 40 Dollar Trees in Iowa and around 20 Family Dollars.

While the items at Dollar Tree all cost a buck or less, the Family Dollar stocks some items up to $5, and higher. The new Dollar Tree chain will become North America’s biggest discount retailer. Specifics on which stores will remain open haven’t been released.
