Selling direct from my website

so I run a website and blog [Writing For A Better Tomorrow] and I’m hoping to sell my book on my website. However, I have a bunch of stock at my house currently and would love to sell those before anything else. The problem, is I’m confused on how I should go about it.

To put it simply: Is there a plugin on WordPress or something that would allow me to sell these physical copies to online buyers?

I hope that makes sense, but please feel free to ask any clarifying questions! I’d really love any and all suggestions/recommendations!
