(I posted this theory in the other
thread, but I thought it worth posting here too, for anyone who cares)
I notice that all the lenses there are relatively old, basically any remaining lens with an aperture ring (minus the FA 31), as well as most of the oldest DA lenses that haven't already been directly replaced (e.g. 50-200 and 100 macro with WR versions) or discontinued entirely (e.g. 16-45).
Now under a standard retail model, PRIC's revenue comes in when the retailer buys stock from them. Anything in stock at the retailer, PRIC has already gotten their money for. When those items are sold, hopefully the retailer orders more from PRIC, generating further revenue. Now what if there were no more for the retailers to order (i.e. discontinued/due to be replaced)? At that point it doesn't really matter to PRIC what those lenses are sold for. But at the same time, if those lenses are to be replaced, they don't want cheap old versions (for which they can get no further money) undercutting sales of new versions (their new revenue generator), so they deliberately price the old versions uncompetitively.
Or it could just be insanity/greed...
