Over at 37Signals.com, an independent software vendor, they figured out an interesting way to reduce credit card chargebacks by 30%. It seems that people making credit card purchases often forgot the company name, or couldn't associate it with the product that they did buy online. Hence, they'd call their credit card company resulting in a charge back.
The solution? 37Signals simply registered a domain name: 37Signals-charge.com.
They changed their credit card configuration so that the domain name ends up on buyer's credit card statements -- and the URL explains what the charge was for.
Simple, effective use of a domain name that only cost $10 to register.
Happy Domain Hunting!
