Applying Coupon Discount before putting in CC info

Hi,

Not sure if this is even possible, but I thought I would ask and see if anyone has ever seen or done this before.

I am looking to see if there is a plugin or add-on or way to apply a coupon on the step 2 of 3, the payment page of the checkout and have an apply button next to the text field where the coupon code is entered and then it applies the discount to the pricing above before you enter in your credit card info.

Probably has not been done, but thought it a good idea to check and see.

Thanks

Such an option doesn't exist in v1.3.x.
Doing it as you described requires reworking how the whole checkout_payment page works.
If it's important for you, you could write custom code for that yourself, or you could write custom ajax code to do it, or you could write custom code to ask for the coupon on another page of the site.

Wondering if anyone ever wrote code for this (coupon redemption prior or entering cc info)?
