Simple rule…….think very carefully before you buy anything! Do you really need it?
There are photography sites out there that allow selling between members after they have been members for a specified time and contributed knowledge and commitment to the site. Even can 'ask' what everyone thinks an item might be worth before listing it. Good thing is they don't charge any fees, so stuff that ends up unsold and goes to e.bay ironically tends to be higher priced to cover the additional costs or owner inflated value view.
I see eBay are changing their terms to give more free listings for private sellers suggesting that the mighty auction house is at last beginning to become eclipsed and feeling the pinch of competition?
I really find eBay unreliable these days and don't use it at all.
Too many scammers and sellers of duff/damaged equipment prevail and eBay generally not interested in resolving disputes. Same with other internet revolutionaries such as Kickstarter and Paypal that I avoid like the plague. All down to the lack of interest in the consumer; read their terms - self interest!
As is said, whatever goes around comes around.
