You have 3 months from the date of your invoice to send a book back for full credit, minus the shipping and handling. The original invoice or a copy of the packing slip must accompany your return item.
Credits or refunds are processed approximately 4-6 weeks from the date that we receive your returned book. Unless directed otherwise: if you paid by credit card, your card will be charged back; if you paid by check, you will receive a refund check; and if you sent us a purchase order, we will issue a credit memo on your account for use toward future purchases or to satisfy an existing open invoice.
