THE FINE PRINT: All items are used unless otherwise stated. All items are described as close as possible to the actual condition including defects. I take extreme care in my packing, but I add insurance to all items (unless you refuse in writing) to prevent a bad situation from occurring. Shipping by FedEx is charged at actual cost, to be paid by winning bidder unless stated otherwise. Please resolve all questions via email prior to bidding or buying. Emails received the last day of an auction may or may not be answered in time. I reserve the right to reject bids from zero or negative feedback bidders and buyers. U.S.P.S. Postal Money Orders are preferred. Bank checks and bank money orders drawn on major banks with a branch in my area (so I can go there to cash it), will speed up shipping. All other forms of payment will need to clear first, which will be at least 10 business days under some circumstances, SO KEEP THAT IN MIND. Other forms of payment (including electronic) possible with conditions applied, please email for additional options. I ship on Tuesdays and Fridays most weeks.
