Checkout and mini cart

1 - Photo - When the person sends the email through the newsletter, do not play to another page, but appear inside the box "email successfully registered" and integrate with the mailchimp. 2 - Photo - The cart pulls the product and the total value. Make the cart pull the freight and discount mode. Both are explained in the photo. 3 - Checkout is working, the payment method is working, both paypal and checkout, just need to correct the shipping. I need it to be stylized to stay as close to the picture as possible. If something is not possible, please advise if something is complex to change the structure or the order. The top menu, side stand and newsletter need to be hidden from this page, 4 - The error messages that appear that the person forgot some information, appear inside the box that the message has been forgotten. 5 - Ticket code is working, but needs to be stylized. The coupon message applied, nonexistent coupon should appear inside the box of the coupon itself. 6 - Enable for when the product is unavailable, the person registering the email and the site administrator receive the alert message. The layout is already developed, just do the sending.
