Processed 3 years online through their Express Tax Online service and all the refund estimates were drastically lower than when I did it myself with the same information. Don't know if they're scraping money off the top or just have no idea what they're doing. They then sent them through when I asked them not to and have refused to take action so I have spent the past 2 weeks running around fixing their mistake. They also take a week to respond to emails, DO NOT EVER USE THIS SERVICE!
