Thank you for this Eric. I really appreciated it.

I had a look at the code, but wasn't sure where I was supposed to copy it to (will try finding some web-savvy local friends to help me one of these days )

In the meantime, I managed to find some info about how to sell Paypal Gift Vouchers. It's not exactly what I am after, but I've been able to make a workaround that allows me to trial the concept at least. (Basically I just used one of my SCCP to be a dedicated webpage just to sell Paypal gift vouchers).

Still hoping that a discount coupon option and/or prepaid voucher option might be available in next round of SCCP

Thank you again for all your help

You would copy the HTML from the discount.html to your shops page.
The promo.php needs to be uploaded to your host.

Thanks Eric for the help. So I can remove the NO Shipping section? Also will that field reside under the present Check out with PayPal button? If so, all my client will need to do will to the code and it will adjust? How do I set the discout to 10 or 20% off?

The Discount code I provide is totally independent of your shop. It's basically an independent Pay Now button.

How do a set the discount? What if I want 20% off? Does the discount button reside below the check out with paypal button? can I change the code for the discount? If it is independent of the cart, how do I get customers to use it?

I am thinking that three years have passed since the first request was made for this to be integral to the cart, does it take that long to create?

Look for this line in the promo.php:)
$discountamount = 99; //this assigns the discount amount to 99.00 dollars if the PromoCode is entered correctly

My client wants to utilize the discount that you wrote of Eric? I am at a loss as to how you set this up. If it is independent do I have to give the URL to this independant Pay Now Button? Will it not cause confusion if the customer has to go to a separate Pay Now page? Do you have a demo for me to see?

On another note, is there any movement at all to have the Shopping Cart Creator Pro it own discount app?

Customers get confused on sites all the time even when you have things to keep them there. The button as stated is an independent solution. I look at it as a temporary thing until CC can come up with a solution. After all discounts are typically temporary. Just make sure you put instructions for the button on your page and set the return url in your PayPal site to your shops location or a thank you page added to your shop. The promo.php has comments to make implementation easy. In the discount.html read each line of code and I think you'll be able to figure it out. I have only tested the code to make sure it worked and don't use it in any site.

Here are the input fields for the promo.php code:

<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="tester@paypal.com">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="item_name" value="My Item">
<input type="hidden" name="item_number" value="123">
<input type="hidden" name="amount" value="100.00">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="button_subtype" value="products">
<input type="hidden" name="cn" value="Add special instructions to the seller">
<input type="hidden" name="no_shipping" value="2">
<input type="hidden" name="rm" value="1">
<input type="hidden" name="custom" value="1">
<input type="hidden" name="return" value="https://www.x.com">
<input type="hidden" name="cancel_return" value="https://www.x.com">
<input type="hidden" name="tax_rate" value="2.000">
<input type="hidden" name="shipping" value="10.00">
<input type="hidden" name="bn" value="PP-BuyNowBF:btn_buynowCC_LG.gif:NonHosted">
<table>
<tr><td>Discount Code</td></tr><tr><td><input type="text" name="promoCode" maxlength="60"></td></tr>
</table>
<input type="image" src="https://www.sandbox.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">

Do I put my client's email unstead of tester@paypal.com? I surmise that that the return value and the cancel value will be his site URL? There are no taxes so the tax_rate should be 0 and the shipping rate will be free on this discount so this will be 0 also?

There does seem to be a lot of work involved to set this up. When it goes live, it has to be error free especially with the potential of 400 plus customers using this discount.

Yup change all the inputs to meet your needs. including the email address. I would setup a PayPal Sandbox account and test it out.
