Delete shop, change sub plan?!

My name is Emil Ernebro, and I have a website via squarespace: www.emilernebro.com.

I currently have a shop on my website but I don't want that anymore. I want to keep everything else on the website and "delete" the shop. I'm sure I can also change the subscription plan and then not pay as much per year since I don't need the web-shop anymore.

What's the best way for me to do this? 

To sum up:

Keep the site just as it is, but delete the shop, (and keep everything else).. and change to a different subscription - which one and how?

I currently have a $228 yearly fee, "professional plan"

 

Kind regards/Emil Ernebro
