Would be interesting to know for other retailers though and how much of this is down to what Walmart sells?

I'm confused by the comment that it failed because it forced single item purchases. Most of my "ecommerce" use is researching and buying one item at a time.

I think in large part the average Walmart consumer does not shop like the average Amazon consumer. They load up a big cart over time rather than pull the trigger on lots of smaller, convenience-driven purchases. So Walmart is going to view a smaller cart size as a potential failure primarily because their operations are not optimized the same way that Amazon is.

It's a failure for e-commerce vendors because it's a spectacular success for shoppers, and the relationship between sellers and buyers is almost always adversarial.
