Hey @SquareMarket ,

If you’re still looking for the solution, try this:

{%- assign item_collections = '' -%}
{%- for line_item in cart.items -%}
  {%- for collection in line_item.product.collections -%}
	{%- assign item_collections = item_collections | append: collection.title | append: ',' -%}
  {%- endfor -%}
{%- endfor -%}

{%- assign item_collections = item_collections | split: ',' | uniq -%}

{%- if item_collections.size > 1 -%}
  //Can not checkout
{%- else -%}
  //Checkout
{%- endif -%}
