Richard:
I'm strictly a collector and have never sold a strike. I've been had by a couple of dishonest people, but I refuse to let them ruin something that I enjoy so much. My regular sellers, like Robert and Christine, can probably tell you that 95% of the strikes I purchase
are by being a sniper. I normally don't bid until the last 30 seconds or so. Sometimes you win...sometimes you don't. I've always been able to finish a casino I was collecting. Just blacklist that seller!
