They are huge liars. I thought they did a really good thing and decided to try their service. But I was only disappointed with their actions and behavior. I sent them 3 books in a great condition. They promised to send me 3 books instead of mine. And I was happy about it, that's what I was hoping for. But it's now been 5 weeks and there're no books. I tried to contact them, but all of my items were useless. No doubts, I was scammed. Honest people never ignore and always stand behind their service or products...
