I guess so. It was news to me as well. Newegg is also doing this.
A couple years ago I was searching the internet for a place to buy Tannerite (binary explosive for exploding rifle targets). I was a bit surprised when the best price was on Newegg. Not just third party tech stuff I guess...
And a side note, got an email 4 weeks ago with an order confirmation on Newegg... only I haven't ordered anything in a while. My account got hacked and the hacker ordered some stuff with my credit card. I called and they recommended I delete my account! Instead I just deleted the stored credit cards and changed my password.
