Payment
We are glad to combine shipping charges on multiple purchases, but it is vital that the proper checkout method be used. When buying more than one item, use the Add to Cart button -- NOT the Buy It Now button. View your cart when you are ready to complete the purchase, and if the total shipping charge is incorrect, do NOT pay. Instead, click the Request Total link at the top right and we will send you a corrected invoice.
Terms of Sale
We strongly believe in full and explicit description of any condition problems or flaws, and in very conservative grading. We stand behind our descriptions -- buy with confidence.
