Shopping Cart – Free Shipping Coupon Not Applying

You can download Magento 1.4.1.1 from here then click on Release Archives tab and find the release version that you're looking for and download it, then extract it, then copy coupon.phtml from base theme app/design/frontend/base/default/template/checkout/cart/coupon.phtml to your active theme folder.

Or just copy the following code:

<form id="discount-coupon-form" action="<?php echo $this->getUrl('checkout/cart/couponPost') ?>" method="post">
    <div class="discount">
        <h2><?php echo $this->__('Discount Codes') ?></h2>
        <div class="discount-form">
            <label for="coupon_code"><?php echo $this->__('Enter your coupon code if you have one.') ?></label>
            <input type="hidden" name="remove" id="remove-coupone" value="0" />
            <div class="input-box">
                <input class="input-text" id="coupon_code" name="coupon_code" value="<?php echo $this->htmlEscape($this->getCouponCode()) ?>" />
            </div>
            <div class="buttons-set">
                <button type="button" title="<?php echo $this->__('Apply Coupon') ?>" class="button" onclick="discountForm.submit(false)" value="<?php echo $this->__('Apply Coupon') ?>"><span><span><?php echo $this->__('Apply Coupon') ?></span></span></button>
                <?php if(strlen($this->getCouponCode())): ?>
                    &nbsp; <button type="button" title="<?php echo $this->__('Cancel Coupon') ?>" class="button" onclick="discountForm.submit(true)" value="<?php echo $this->__('Cancel Coupon') ?>"><span><span><?php echo $this->__('Cancel Coupon') ?></span></span></button>
                <?php endif;?>
            </div>
        </div>
    </div>
</form>
<script type="text/javascript">
//<![CDATA[
var discountForm = new VarienForm('discount-coupon-form');
discountForm.submit = function (isRemove) {
    if (isRemove) {
        $('coupon_code').removeClassName('required-entry');
        $('remove-coupone').value = "1";
    } else {
        $('coupon_code').addClassName('required-entry');
        $('remove-coupone').value = "0";
    }
    return VarienForm.prototype.submit.bind(discountForm)();
}
//]]>
</script>

• First You need to disable free shipping and enable flatrate.
• After that you need to set two different rules from the shopping cart price rules.
• One Will be for free shipping over order of 100$ and another one for 5$ discount along with free shipping discount (//your conditions here).

Hope this helps.
