Ask HN: Does your business offer promo codes?

I'd like to get a sense about the value people place on promo codes. Some things I'd like to talk about:

How important are promo codes/discounts/coupons to your purchasing decisions?

Does your business offer promo codes?

If your business offers promo codes, please describe how you use them.

For those who don't want to share details about their business here, I created a survey that I would be grateful if people filled out.
