For that you'll want to implement the "checkout API" of HikaShop in your plugin: [ www.hikashop.com/support/documentation/6...tation.html#checkout](https://www.hikashop.com/support/documentation/62-hikashop-developer-documentation.html#checkout) In your plugin, you can easily load the current cart data with: $cartClass = hikashop_get('class.cart'); $cart = $cartClass->getFullCart(); And you will have the information of the id of the selected shipping address in $cart->cart_shipping_address_ids And you can use such code to load the details of that address: $addressClass = hikashop_get('class.address'); $address = $addressClass->get($cart->cart_shipping_address_ids); In your plugin, you'll want to implement onCheckoutStepList to add your new block to the list of available blocks so that you can add it to the checkout workflow in the HikaShop configuration. You can potentially implement onBeforeCheckoutStep to check that the address has already been selected (but depending on how your checkout workflow, this might not be necessary). You can implement onCheckoutStepDisplay to display the list based on the cart's shipping address And you can implement onAfterCheckoutStep to save the selection of the pickup list in the cart. What I also recommend is to configure a custom order field in order to store the selection of the pick up list. That way, you won't have to handle the display of your selected pickup list in the order, in the email notifications, in the invoices, etc as it will be done by the custom order field system. You can see an example of that with the plugins/hikashop/userpoints.php plugin which can add its own points usage block to the checkout in a similar way.
