I have 4 tickets in hand, you can buy 1 or more than 1. They have the holograms, serial code, ticket face value, and QR codes on the back, and I ordered them directly from Burning Man in December. I have the receipt as well.
They're $420 tier tickets that I got for a group of friends during the presale around Christmas, but we just found out that we can't go. You can have them for $280 each (or a bit less, if you send me a good story about why you're going!).
I can overnight ship them to you within the US (included in price) so that you'll get them the day after you buy them, or you can pick them up in San Francisco (SOMA, right next to all the freeways and the Bay Bridge). I can also drop them off within SF, the Peninsula, or the South Bay, for an extra fee.
100% positive feedback over 10 years, I guarantee the tickets
