Welcome to the WooCommerce community!
I understand that you would like some guidance with the FreshCart theme, is this correct?
You can view the FreshCart theme support documentation below, which may be helpful in guiding you:
How to set a price such as 3 for £15 or pay 2 get 3. I am looking all over plug in but could’t find it. I only found bundle but It is not what I want.
This would require a plugin as this is not a built-in feature of WooCommerce core.
You could have a look at the Buy One Get One Free extension which can help you achieve this.
WooCommerce.com offers a 30-day refund policy which you can take advantage of, allowing you to test the extension, and make sure that it is what you are looking for.
Additionally, if you have a valid license for the FreshCart theme, please can you reach out to us directly via WooCommerce.com → My Account → Support. You will need to log in with the account used to purchase the extension before you can access that page.
As per the forum guidelines, no support for premium extensions/themes is done here but we will be happy to assist you further from there 🙂
Hope this helps!
