I've heard (in some places) in Mexico you can have groceries delivered to you from Walmart[0]. I was told about it, but after finding that article it seems a Walmart owned business, mind you this article is from 2014, and I heard about this in 2007 ~ 2008 from someone who was living in Mexico at the time. It is very interesting to see businesses other than food places deliver goods.
