Hello,

I have provided the code and it has removed the price from the Related product and in the grid: https://gyazo.com/86e366eeeddd98b93be147021c52cf55

Add this code to remove the price from the sidebar:

body .price .amount {
   display: none;
}

The quick view also does not have the price: https://gyazo.com/223d1b77ec1e819fa582b5dd40e38151

Please give me the URL where you still see the price, please clear the browser cache.

Best Regards
