Live chat buttons and contact forms were not designed for the fast-paced and highly competitive ecommerce market. They were designed for B2B and SaaS businesses. It's 2019, your customers have so many options to choose from, and they won't want to (and don't have to) wait for someone to get back to them. Commerce has always been done on a 1-on-1 conversation, and so this is our mission to recreate. Go ahead, visit Allied Cycles and click their call back button. See how fast they respond (during opening hours) and imagine how many more sales you would make if you could offer the same service.
