A little story
Back when I built my video pin I ordered some parts from virtuapin. I ordered a bunch of cabinet parts from them. Leg brackets, a plunger kit and BY ACCSEDENT I ordered 2 sets of backbox hinges.
I obviously ordered parts for one cabinet. Except for the two sets of hinges.
BEFORE my order was processed and shipped, the seller sent me an email confirming that I did indeed did want 2 sets of hinges. They could have charged me for two and mailed me two and then dealt with it after the fact, but instead they were proactive and fixed my obvious mistake before it ballooned into something more.
Whomever the eBay seller is in this case should have obviously noticed the mistake. (No one would pay 75% over the asking price for a product, especially on an EBay "make an offer" ad). This is clearly a case of a greedy eBay seller, despite the mistake that was made.
I will avoid buying from this guy, thanks for the heads up.
