Stores for Mass Effect 3 are the stores from where you can buy gear, such as Armor or Weapons, and a wider array of things. This time around, you buy directly from terminals, there are no longer merchants taking care of the transactions. In order to buy something from a terminal, you need credits. Credits can be earned by completing Missions, finding datapads or searching throughout the galaxy.
Alliance Requisitions can be accessed through the Procurement Interface in the Shuttle Bay of the Normandy. By the Alliance Requisitions terminal you can purchase anything from the shops you have visited around the galaxy. This comes with a drawback, any item will come with a 10% price markup.
