you are correct. there was a bug and my questions weren't posting. thanks.

well, we'll just have to try that

Well, of course, but I am taken aback that i couldn't find anyone doing it even in industries where this tactic was widely used (web hosting, cheap retail, etc). If there is some negative effect of this that i don't know about, i dont want to do it and then, you know, have my account suspended, or get a lot of phone calls to customer service. It just seems weird how absent these are. They used to be very common in adwords ads. It's not like coupon codes are less popular than they used to be.

It's been years since I've had a discount I could offer over PPC. I remember when I was a young search monkey, that companies would offer the coupon code directly in the ad copy. However, an inspection of ads on various queries, I don't see anyone doing this.

I want to, because of course a concrete offer should certainly help CTR right?  But, not finding any referent examples of other companies using the coupon code freaks me out. Is there a drawback to posting the code directly?

Haven't worked with discount codes in years. Researching the ad copy I found very few sites putting the promo code directly in the ad copy. I thought this was a standard practice for increasing response.

Do you know why companies with active promo codes don't use them in Adwords copy?
