Bing is testing yet another way of showing free shipping in its search resutls. The current version of the free shipping label is showing the qualifying purchase amount.
Previously, Bing tested a “truck icon” that shown the qualifying purchase amount on hover and also “free shipping” info without any specific amount right next to the visible URL.
The new label is designed to streamline the shopping experience by clearly showing the amount customers need to spend to qualify for free shipping at a glance.
