As a business owner, imagine that I’m just doing a research, I don’t know exact dates of my holiday (it mostly depends on your availability) and I’m not sure how long I want to stay. I need to find out the options, consider them and talk with my partner. If we would talk on the phone, you would give me dates but what’s next? I would hang up anyway to think about these dates. And that’s not closing a deal. That’s inconvenience for me, because I need to write them down anyway.
Coupon: Unlike the job application, you probably know very little about someone who has stumbled upon one of your online coupons. But if they find the coupon valuable enough, they may be willing to provide their name and email address in exchange for it. Although it's not a lot of information, it's enough for a business to know that someone has interest in their company.
