Toys and Treasures review for Charge Me Later, Wholesale app

This app never worked quite right. I was trying to use it to do pre-orders, and somehow the app did not prevent people from using the "Buy it Now" button and bypassing the draft order page. This resulted in me having to refund the orders that made it through, and eat the ~2% credit card fee charged by Shopify. I contacted support, who to their credit, responded pretty quickly. They asked for access to my site and made some code changes. Things seemed to be working for a little while but then today out of the blue our checkout button stopped working. I removed the Charge Me Later app, and restored my theme to how it was before their changes. Voila! my site is working once again. I have no idea how many sales I lost because of this.
