It was the same Swingline stapler, on the same Staples.com SPLS +0.22% website. But for Kim Wamble, the price was $15.79, while the price on Trude Frizzell’s screen, just a few miles away, was $14.29.

More than that, Staples appeared to consider the person’s distance from a rival brick-and-mortar store, either OfficeMax Inc. OMX +0.96% or Office Depot Inc. ODP -3.60% If rival stores were within 20 miles or so, Staples.com usually showed a discounted price.
