Honestly in most cases it's never even asked. If you set up and account you can actually fill out your shipping info on line and directly print your label. Then all you do is drop off your package and they don't even ask you anything:)
Seriously, this is the exact way to do it. Don't have to lie and no questions asked.
I've shipped 30+ trades on beer advocate and this is the way to go. Print, drop off, and no questions asked. I also like to include an empty can with a few nuts, pennies, rice, or anything that will rattle. It helps mask the sloshing sound.
