Earlier this week, I was on Walmart.com shopping for an item. I added it to my shopping cart, but ultimately decided not to buy it. I got an email today with the subject line: You left something in your shopping cart at Walmart.com.
I had forgotten all about it. They reminded me, and the idea of buying this thing crossed my mind again. This is brilliant. I don't necessarily want every company to copy this technique, but this is the kind of thinking I want in retailers.
