Bryan and I were working and going over some existing code for the cart/invoice rounding feature. This deals with the cart/invoice on a whole. We have been working on this project for the past couple of days. We keep getting closer and closer and pushed up some new changes today. We only tested things on data 6 but have plans to push code to all other servers very soon. The only current problem deals with exchanges and doing negative invoices or returns. There seems to be a sales tax bug that only shows up under certain scenarios. Those are the hardest ones to find and debug.
