These checkout payment and shipping pages have already been merged into one. Now I also want the login / create account page integrated, and everything to update using ajax. The sample page in terms of style and functions is the checkout page at [url removed, login to view]
Fields need to toggle according to which option the person selects. ie. If they login, then there registered address should appear and they should be able to change it if they want to by going to their account address book.
Once customer logs in, their previously stored products should also appear, and should be able to be removed in a similar fashion to the panic site.
If it is a new customer, they should be able to click a radio field which will display the form to collect their details.
The order total needs to update according to the shipping cost and the coupon discount should also update the order total. That is, there should be a subtotal which adds up all the products, then it should say postage, then IF THERE IS A DISCOUNT, there would be another line to reflect that, otherwise it would then display the total.
Sub-total : $25.00
Discount (**Only if valid): $10.00
Payment area should look exactly like [url removed, login to view]
There should be NO CHECKOUT CONFIRMATION PAGE. This is a one page checkout.
If you are also able to make the shopping cart at the bottom of the store pages to update using ajax, I am also open to this.
