Those whom buy the same coin every time it appears on eBay regardless of the cost need to be cast into the sea as sharkfood...it accomplishes nothing but driving up the price for the same coin they have on sale elsewhere on ebay in buy it now under a different seller name; they are fooling no one, and the effect is keeping regular buyers from ever getting said coin because they refuse to pay ridiculous inflated buy it now prices. Examples include India 1/2 Rupees and Dominican Republic Pesos. The list goes on and on.
Only one way to combat this....buyers refuse to pay for hyperinflated buy it now prices, which means these bright idea people will be stuck with the goods. It only takes a moment to hit the delete button. But then again we've seen the same coins at the same prices from the same sellers for years...they don't seem to be getting the hint.
