I found ebooksprime through google shopping and needed 3 specific ebooks that i was doing research on, i sent a message to them and to my surprise I got a reply back within 2 minutes from their team. I was extremely happy with there service and they were able to put together a great deal for me.
I have used them for my ebooks on 3 different purchases and can verify they are great and have better prices compared to Amazon and B&N.
