For my business, I've decided that to gain growth and traction, I wanted to make a coupon code that would allow one to be elligible for 1 specific item for free off of my online store. I aslo would like this functionality for close friends if I ever want to help them out or give them a gift. How could I do this so that if there is no charge, to require no payment information as to not seem like a scam? (As in "Why does it need my credit card if it's free???") Does shopify support this kind of functionality on the basic account or is there any other way of doing this?
