Anyway, I found a map plotting what everyone says and posted it below. I also found a cool website dissecting what everyone says with a big map and charts breaking it down by state. You can even input your data according to your hometown!
I also refer to the shopping vehicle in which you store your items until you check out as a 'shopping cart', but it seems everyone around here refers to it as a 'basket'. I refer to the tiny container you grab if you need just 3 or 4 small items as a 'basket'. So, it must be a regional thing. What do you call it? Cart or Basket? And where do you live?
