As a customer you can go through each advertisement from each store and plan out your ‘strategy’ well ahead in time. It is humanly not possible to be at more than one place at one given time. The best that can be done is to make a list of all that is to be bought and from which store. Short listing and prioritizing will help decide what to go for first. All stores have different opening times. Checking out the times of each store on Black Friday Ad and planning accordingly will be the call of the hour.
