Grocery shopping

When you go shopping at a grocery store-  how do you do it? I was thinking about this today while shopping at a Super Walmart for our weekly grocery run.  Before you go in to shop: Do you write down a list or just make mental notes and go in.  When you walk in your store do you go straight for produce or do something different?  Do you go up and down every aisle?

We usually write a list and then get the produce 1st and then go down each aisle; from one aisle to the next to get what is on the list or if something shows up that we might want to eat.  The hard part is the balance of the meat aisle and fridge aisles and then keep going up and down.  Granted we usually buy our meats @ BJ's and try to get our produce at the farmers market @ Lake Eola.  But when we do we try to get the meat and then walk down the aisles.

I know this is pretty random but when you are looking at an entire supermarket shop its is kind of fun to see what peoples tendencies are.  Some we would see going down the same aisles and others would just go right off there list.

What do you do when you walk into a store?
