I just saw this on Facebook. My answers seemed 'normal'--and they are, for the Midwest, at least. I was surprised to see that people from the South--and New York city--use totally different names for these common items. I'm interested in seeing what everyone here 'calls' these items; I'll post my answers after the photo:

My answers were: Grocery/shopping cart, BackPack, Soft Drink.
Other names were: 'buggy', soda/coke/pop
