Downtown camera pays no more than half of what can be found on ebay.
-) a camera store selling used cameras wants to make profit on them
And before that has to come up for its handling costs (personnel time involved, having a store open for a client to come in)
-) a camera store here in Germany has to include VAT in its retail price of used stuff, and has to give 12months warranty
-) with Ebay one has the hassle to describe in detail things (heirs ignorant on matters already here get into difficulties), take photographs. And has to wait for a buyer, package all and mail it and then have to wait for the money to come in.
For those few still having a respective dealer downtown such is a valid, hassle-free alternative, even more trustworthy, nonwithstanding the chance of getting less than on Ebay.
