The High-Speed Trading Behind an Amazon Purchase

I've actually started switching grocery buying to walmart - because they do have the best price, and they have free shipping.

With Amazon it's annoying - I have to keep items in the cart for a while to see how the price ends up. That's worth it for expensive electronics, but not groceries.

Watch out. Walmart gets different SKUs for the products they carry. I've seen snacks that were a couple of ounces smaller, for example. Also, their meat and produce is much lower quality than other places.

I've seen items vary wildly at walmart as well- once saw a $3 item go to $18 for a day.
