Getting ahead in life, business and sales is about doing more and doing more than is expected.
Check out this rendition of an incident by Frank Rambuskus:
"A while back I put a job out to bid to redesign a website. Many people placed bids, with the usual links to their portfolios and customer testimonials.
One web designer, however, went one better: She actually built an all-new site per the specs in my job posting, and sent me a link to it with a note saying that, if I chose her, she could have the site live on my server almost immediately after receiving payment.
She got the job!"
This is an example of a salesperson giving value first before expecting anything.
