Starbucks is testing grocery store end caps modeled after the coffee chain's decor. The displays in 12 cities use wooden borders and fake-tile backsplashes to mimic the warm interior of a coffee shop and let the Starbucks products stand out in the coffee section. Jeff Hansberry, Starbucks' president of channel development and emerging brands, says the special end caps are selling coffee products at two to three times the normal rate.
