Let's give the gentleman a break.
Due credits paid, he's the first to pay in this groupbuy (I can confirm this). And indeed this groupbuy has been taking longer than first expected... The gentleman is right in this respect. Although it can be argued that when you commit to a groupbuy you expect that you have to wait for a while but you never know what happens in life and sometimes in an emergency you may need extra funds.
Personally I think the people who gave no response to the invoice are more responsible for hindering the groupbuy. Dropping out is fine, as said, sometimes people may need extra funds, or may lose interests in the sets after having been kept waiting for long. But no response...
I didn't mean to have the gentleman "publicly slandered". I just wondered if anyone would be willing to take his order. Was a little bit shocked about the Paypal dispute, though.
Anyway, we've finally reached the production stage. This is my first groupbuy and I know I can do better next time. Sorry for all the delay and inconvenience caused and thanks for everyone's support!
