This coupon code is a slap in the face
This is a pretty ridiculous complaint.<p>First of all, giving everyone a referral URL works great in a web only world but what if you're advertising on a Podcast (or <i>gasp</i> print or radio), is it easier to tell people to type in www.mysite.com/coupon to their browser or is it easier to tell people to enter COUPON at checkout?<p>Secondly, the amount of people who are going to have this adverse reaction to the mere existence of the coupon code field is vanishingly small. Most customers who don't have a code will just ignore it and move on (and actually many who have been told about a code will not even use it) only a small minority will bother searching for a code to enter when they don't have one.<p>Whatever web site had a coupon code field that made you this angry probably had at least 20 much worse UI violations they should prioritize above trying to eliminate the coupon field.
