I lost a few thousand a while back becasue i ignored th signs. I was weary, but i followed through sent $2500 worth of cues. 2 weeks later he wanted more, I figured there was no problem so it was a good buyer and i sent another package.
Turns out everything was paid for with stolen credit card numbers and all the cash was taken out of my account. He had the cues I had a bill, the problem was it took 30 days for the bills to come out and the actual owners to find the bad charges.
I got lucky, one of the packages with some rare cues was returned because they said it was undeliverable.
I actually just had a negitive feedback on ebay, because a buyer from a country i wont ship to won an auction. I returned the money and said thats not a country i ship to. My listing said i only ship to the cont. US.
Ebay said they couldn't do anyhting about the feedback. i'd rather have a neg feedback. than loose $500.
Good luck
