I ordered a three-month subscription for my granddaughter and accidentally selected the wrong age category. When I received the email stating the first subscription was being mailed, I noticed my error and sent a message back asking them to change the plan. Elephant Books immediately responded to my email and agreed to send out a second (correct) set of books at no charge! I was informed that my granddaughter could keep the books from the wrong age group and gift them to someone. Wow! I'm so impressed with their customer service! You've won a loyal customer!
