There are seven store related user permissions. The first six automatically default to Yes for all Users. The View Item Cost in List Items permission automatically defaults to No.
Go to Tools > Manage Users & Permissions > User IDs (click on a UserID) > User Permissions (left) to set the permissions.
Note: After changing the permissions, you'll need to logout and log back in for the permissions to take effect.
