I can't say enough positive things about my experience with Ziffit, especially Natalie from admin. This was my first experience selling books on line and she has been absolutely awesome. She responded to my questions right away. Some of my boxes were delayed, but she patiently worked through locating them. I appreciated her constant updates about my trade! I am selling these books to raise funds for my grandchildren's school, a small private school. Thank you all so much for a great experience. It has been a pleasure and I look forward to selling the books I have left with Ziffit ...
