The thing with eBay: The inventory replenishes every day, by at least several hundred new items. It’s much different than when we used to buy our records in physical stores. If you didn’t get to your favorite store for a few weeks, you may not have missed anything. Or, if you happened to walk in at just the right time, you might have been in luck for a major score. With eBay, you get the sense that if you miss something one day, don’t worry, it’ll eventually come back. The challenge with eBay, versus the traditional record stores, is that there is only one item and you are competing on price with every other collector in the world. That’s one of the reasons the prices on eBay are high versus what you might find in a store, and why so many of the top sellers — such as Euclid and Jazz Record Center and Atomic — do a lot of their business on eBay these days.  What do you think?
