@0xabad1dea Grocery store (and fuel) brands vary, too.

I once took a visiting British friend to Fresh and Easy (which was owned by Tesco, so I figured it'd be a little more familiar). Then he wanted to get a 2-liter bottle of Dr Pepper for his professor, and I was like: “We are not buying Dr. Pepper here.” Took him to Albertsons where the same soda was $2 cheaper (99¢/bottle).
