Man! Walk a dog for a bit and the whole world turns upside down.
I know everyone likes to warn all the others about some slight, real or imagined. Let the two parties work it out or not. It is certainly not incumbent upon me to warn others unless and until I have taken all the remedial actions available. Even then I would be hesitant to disparage another on a public forum. Too many members are too quick to air their problems, sharing the misery as it were. If you buy on the internet and get screwed, take your medicine. I can look after myself, nobody else needs to play "Better Business Bureau" for me.
If you got a bad pipe, take it up with the vendor. Product not received? Contact them or PayPal or your credit card issuer. Why publicize it? Once you've exhausted all your options and you still feel aggrieved, tell it to the Padre or Sky Pilot. Buying on the net, especially from home based "mom and pops" entails some risk. We are not all friends here, honest and trustworthy. Aliases, avatars, etc. should lead one to exercise great discretion before parting with product or moneys. "Always expect the worst from people and you'll never be disappointed. Sometimes you might be pleasantly surprised."
