This could be huge and really good for consumers. But I wonder how much this will hurt Walmart B&M stores.
I remember very clearly before Walmart.com instituted their free shipping minimum (probably about 4 years ago) when I used to order say a huge bottle of Pine Sol for about a dollar and have it shipped free by itself. They also would throw in all these great samples of different shampoos etc.
I never understood then why they couldn't grab more of the online retail market back then. My guess is Amazon just has been so cost effective that many people don't even bother checking other websites before purchasing.
