pinkyrose,
You can start to watch out for sales. I think normally in March/June there'll be baby fairs. June might be a bit late cos it's hard to shop much with a big belly. Maybe can start with baby bed, clothes, mattress+covers+blankets. Sometimes there are very good offers for big ticket items like carseats and strollers, just keep a lookout. You can buy perishable items nearer to EDD, like diapers, diaper cream, ru yi oil, etc. As for electrical items, depends on you. I bought closer to EDD for #1 so that the warranty will start later. Some stores let u reserve the unit and warranty only starts after you collect.
