The end of crazy ebay prices?

[Akiko]

Some sellers increase the price of their items drastically when they are running low, are they are temporarily out of stock, this is a sales tactic to keep their current listings live and avoids loosing the sales history and search ranking for that particular item if it was simply allowed to sell out, so I imagine this is just eBay's way around the problem,  the intended targets are probably the likes of the seller in the link below.
