In my state if I photograph a wedding and give the client a flash drive of the photos, I need to charge them sales tax on the entire wedding. If I just deliver the photos online, there’s no sales tax. If they (or a family member) later purchase prints through their online gallery that are essentially drop shipped to them? Who the hell knows.
