Hi,

I have the below code in Settings->Check Out → Addional Scripts Section

{% if customer and customer.orders_count == 1 %}

Thank You for Your First Purchase!

As a special gift, here’s a 10% discount on your next order:

Use Code: WELCOME10

{% endif %}

Will it stop working after the 31st of December this year?

Thanks
