I do the same, and purchase extras to every show I think will sell out, especially if they are weekend shows. I only get really burned when I buy tickets over $70, or Sasquatch passes (I lost money on Sasquatch passes last year too). The worst part is that I operate as a scalper, but never make money on the hot tickets because I sell them for face. I lose a lot of money on the not so hot tickets. I should get out of this business, because being nice is rarely rewarded.
