Are chat bots for my Shopify site worth it?

I've been looking to install a chat bot on my Shopify site, selling clothes in the $80 - $150 range. Any recommendations? I've been told that chat bots work better for products with a higher ticket price in the high hundreds / thousands, otherwise it's just a distraction.

If you've used a chat bot before, do you find that to be true (high ticket price vs lower)? Are they actually effective at generating sales, and how effective is AI for resolving tickets vs people? I have a feeling customers would get really frustrated with using AI.
