Walmart.com is taking a risk by adding banner ads to its product pages, at the top. They aren't exactly engaging high-end advertisers either ... I was shown a "Free dinner at Olive Garden" ad (pictured). First off, the link sent you to a very scammy solicitation for "2 Silver offers, 1 Gold offer, and 1 Platinum offer". Second, Olive Garden wasn't mentioned anywhere. And third ... Olive Garden? Ick!
So, is Walmart saying that e-commerce doesn't work for them? Or are they simply maximizing revenue from the thousands of people who visit their site every day from dealnews to buy something and then go, "Wait, I'm not shopping here. It's Wal-Mart! I'd rather eat at an Olive Garden!"
