People are lazy and greedy and don't think of looking elsewhere. They also get caught up in auctions.I remember years ago an
eBay seller offering a certain mobile phone (brand new in sealed box) which normally sold for £100 for £75.00.
He got quite a few orders. Buyers were most pissed off when their phones arrived direct from Amazon who were offering them for sale at £50.
Everytime the guy got an order on
eBay he bought one on Amazon and had it delivered direct, I thought it very funny and quite admired the guy for his quick thinking, but buyers seemed to think he had ripped them off.
I once sold a second hand Cambridge Audio phono stage on
eBay for £10 more than a new one cost from Richer Sounds.
