Add to cart/checkout product automatically on Adidas India

I would like a method for immediately adding a product to cart and checking out from Adidas India. The shoe is very limited and therefore automating this process is the only chance of securing the product. Ideally, this would be some sort of easy-to-use program where I could input my information beforehand (billing, shipping, shoe size, etc) and simply begin running the program a few minutes prior to release. Thus, this would allow me to fill out a form before each release with custom information and the checkout process would be done accordingly. Adidas India does not utilize Captcha or further securities so this would be a basic program. I would like to have this done by 6AM GMT, November 17, 2017.
