First of all why would you purchase software that didn't have the features you wanted or was buggy without evaluating it? Even so, many vendors accept returns.

First of all why would you purchase software that didn't have the features you wanted or was buggy without evaluating it? Even so, many vendors accept returns. And if you think spending countless hours implementing and testing features in a codebase (that you have to spend hours just learning, and that is if you're lucky and already are familiar with the programming language its implemented in) is "better" than just paying a vendor to do it, then probably no rational argument would convince you otherwise, and I would withdraw my objection.
