I am not currently an Agora user, but am thinking of using this for my website. Before I do, I want to make sure that it will meet my requirements. I am located in NC where there is a 4.5% state sales tax and the county sales tax varies from county to county. I want to make sure that this is something that can be easily set up before I decide to use Agora. Is it possible to set this up by just entering the county name or do I have to include zip code ranges? Also, does Agora integrate with PayPal Pro? If I already set up zip code ranges in my PayPal account, can I tie that information into my Agora shopping cart? Do I need the Gold Version for this? Thank you.
