They have sent out a number of emails about their large digital inventory, including a lot of mfr refurbished items, so I suspect their money is going into digital. How many Rollei TLRs do you think they'll sell in a month? More than four? So why have more than four sitting around? How many D5100's at $400? Ten, fifteen, twenty? It's not hard to see where the inventory money is going.
When they're selling something on eBay I often check if they have a comparable item in stock. Sometimes it's a better deal on the site, sometimes on eBay. Often on eBay they offer free shipping which makes the difference. A lot of their eBay stuff has minor stuff wrong with it that, on the site, would not allow it to reach BGN level by their standards, but on eBay they don't use those ratings and just say, well there's haze behind the rear element and "might make for some interesting effects!" Indeed, such as flare and low contrast.... Their UG prices are so low they're often going to do better on eBay with such items.
