On July 2016, Adwords updated with new value added feature “Price extensions”. It enables advertiser to show prices by selecting types of products, by my personal experience, this feature increased my click through rate gradually.
Previously this price extension services is only enabled to text ad extension on desktop and now it is started showing on mobiles as well. Also as added value, on price extension we can set mobile URL which is optional now to advertiser.
