Amiami Cart Adder от marvinody

Install the Addon, go to Amiami's page ( https://www.amiami.com/eng/ ), find a product you want that's closed for pre-orders, and open the addon and link it in the ghost-cart in the addon. Once you have it loaded, you can wait until the exact time pre-order opens and hit a single button to add it to your cart & go to the checkout page.
