Generally, most places are pretty good about having packaging that doesn't label what the item is. Most places know that a good majority of their customers do not want to advertise their hobbies. You might want to stay away from ordering anything called a "bong" because "bongs" are illegal, to my knowledge. But, if you order a "water pipe," then you're okay. I can't tell you anything about billing. If you find a place that accepts PayPal, then the only thing that will show up is that you used PayPal.
