I'm sure it's just me, but I've never felt bad or weird or bad or even cared much about the possibility of paying 20 bucks for something vs 19 bucks with a 5% off coupon code. That one dollar savings doesn't seem worth the hassle of spending 20 minutes on Google. I'd rather spend that 20 minutes billing 100 bucks/hour making a website for someone.

Reading these comments it seems there are a lot of people on Hacker News who seem quite passionate about the idea of getting the best deal they can and not "feeling like a sucker".

Which is fine, but it's definitely a feeling I don't experience. Maybe I'm just weird.

With the topic at hand, having maintained an online shop for a client for several years, I see that they use Coupon Codes as a customer service thing. Didn't like your product? Here's a onetime use 15% off code so you don't hate us. At least that's how they used it. So I always ignore those fields.
