Does anyone have any code to enable me to not show prices on particular products in my shop.
I am only allowed to remove it from all products in my template. 

First, edit product & add tag: noprice

Next, add this code to Home > Design > Custom CSS

.tag-noprice .product-price {
    display: none;
}

Dear Tuanphan,

Thank you for the answer, 🙂 But I dont seem to get it to work.   

I added tag and custom CSS but the price is still displaying. Should I use a ID as well in the CSS code? 

"r products in my shop"

You mean shop list page or product detail?

Above code for shop list page.

Can you share link to product detail on your site?

Oh yes - sorry. 

I refer to the product detail pages.  I have made another shop list front manually so it is only the product detail pages I need to alter.

Here is a link to one of the products I want to hide the price on:

Did you add tag: noprice?

I just tested on my demo site (SS 7.1), this code will work

.tag-noprice .product-price {
    display: none !important;
}

OMG it worked! Thank you very much! 😊😊😊

Actually I have another question.

Do you know how to customize the button on the product details page? 

I want to hide the button and mail signup box on certain products. Pls. see link below:

.tag-nobox form.product-restock-form {

Add tag: nobox and use above code

It worked like a charm! Thank you !!!   😊
