Here is a (typical?) example of an ebay marker-uperer.
An item sold, (for what I consider a likely fair price), one week and was back on the auction site the next week at FIVE times the price of the item realised the previous week. Pics of the ‘two’ items most certainly appear to be the same item, simply rearranged for the new pics. There may have been some wiping down to clean the parts a little, but no more than that.
If anyone sees items offered by “rawengineering” might well need to be aware of this type of ‘dealer-marketing’. He also has at least one other item which has been grossly over-inflated, compared to the usual auction values, so this was not an isolated instance.
I recognise that dealers have to make a profit, but not to simply try ‘ripping-off’ any purchasers like that. They may well buy things at much under market price (workshop clearance), too – and some find items from house clearances for absolute peanuts.
The seller, above, may be one of the extreme examples – but I expect there are others.
