Two books were sent to my son, thin Dr. Seuss books I might have found at the dollar store, along with a bill for over$25. I emailed them to tell them if they wanted their unsolicited shipment back, to send me prepaid postage. Weeks later, they did, so I sent the books back within a day of recieving the postage. Receiving bill now addressed to me, instead of my son. Called their number and lady indicated she had no way of knowing if I'd sent books back. Sounds like a scam to me. My mistake- should have insisted on prepaid CERTIFIED mail postage.
