Thankyou very much for the post dusty, greatly appreciated.
And no its not as simple as just selling someone elses gear. The other guy in question is a friend I have known for years before paintball. We started the sport together, and clubbed together getting gear etc to share. That is why we were using this as a joint account, with a joint sale. All our gear is together in one place so we just did the one thread so as people could save on shipping/buy multiple items more easily. In the past it has worked perfectly, without a hitch.
I would also just like to say that over the internet it is remarkably hard to extract how a person is truly commenting. Many of the so called inflaming comments were not intended in that manner, and were just misconceived. Like I just posted previously, I am still for some crazy reason willing to just take the bloody marker back and give back your money. I feel this PayPal dispute you have filed is simply rather unfair bearing in mind a full refund has already been offered countless times. However, if you do wish to continue with the dispute, I shall indeed fight it, citing every piece of evidence here. I will be perfectly happy either having the marker back, or the money. It is your choice.
Lastly, if you were to win this paypal dispute, would you even send the marker back, or were you intending on keeping bith the money and the marker?
