half.com quick sell mycroft plugin

So Pages to Prisoners sells books that seem somewhat valuable and probably won’t get requested by folks in prison on Half.com as a fundraiser.  All proceeds go into supplies and postage for the project.  We get a lot of books sometimes, and I wanted to streamline the price lookup process.  So, I made a MyCroft plugin for Half.com’s quick sell form.  You can install the extension here.
