Paul did a great job! We did use to only show coupons in case coupons were setup for whole cart or if the cart contained items and then that had to be changed to work with new discount code changes. We are however working on a fix today to get it like the way it should be.

As for Google Checkout issue, it’s a great point. We are only going to start showing up for GBP and USD carts for not and later on even make that more specific so that USD carts show Google Checkout only for merchants in US and GBP only for merchants in UK.

Thanks for helping us improve and also for coming up with a workaround already so there’s no pressure ;)

Yes. Ideally the coupon field should be populated from an argument in the URL so the user gets some visual feedback. I haven’t actually tried this yet, but it should hopefully be quite easy to set up in the form.

>> I only want the coupon field to appear if I give the user a particular URL, and I will only give that URL to customers who have coupon codes.

Just thinking: In that use case wouldn’t it be easier to have the coupon code embedded in the URL? In that case, no need for a coupon field at all, the discount could appear automatically.
