Droppin HZ Car Audio review for Hulk Product Options

0 Stars wasnt an option so this gets 1. The app will display the correct up charges for my options but it will not charge them in the cart. This app has cost me a ton of time and money. I tried communicating this with the developers but I was just told that I needed to remove certain characters from my options. Some how / and ? are not compatible with this app, or so I was told. I removed all special characters and still have the same issue. This is a HUGE waste of time and money!
