Remember that the fashion industry has revenue that absolutely dwarfs the tech industry. It's so far beyond that it's not even funny. People can't go naked, they need clothes, and most of the time they prefer to try them on, see how they look and fit, then purchase in person.
Then there's food which is even larger. The online ordering of groceries is a drop in the bucket. You want fresh food, you're going to have to go and hand pick it.
Not surprisingly Wal-Mart has a foot in both camps.
Does the fashion industry really "dwarf" the tech industry?
Random googling tells me that the global fashion industry does about $1.2 trillion in revenue per year. Microsoft, Google, Apple, and IBM together do a bit over $400 billion per year, so about a third of that, and that's only four (albeit large) tech companies. I'd be surprised if you couldn't more than triple that number after you accounted for all the other tech companies in the world.
Samsung's electronics division does almost $200 billion/year. Foxconn does $120 billion. Hitachi is also about $120 billion. HP is about $110 billion. Amazon is $75 billion. Intel is $50 billion. Need I go on?
