I am like all the other sellers on Ebay, I like to see bidding, Sometimes if t are no bids, I will revise and add a buy it now, or extend the auction. I will not repost the item to sell; I will have a garage sale and sale it then. So if you want it, bid on it. Be sure and check out my other auctions and thanks for looking Items sold as is, NO RETURNS, So Ask Before You Bid I do Ebay to keep me busy, I am retired, and this is my way of having a little fun, and I hope you have some fun as well. I will combine shipping, If you purchase more than 1 item, and I can put it in the same box or The same envelop; shipping will be the same, no extra charge, Unless the weight is really heavy I give the best description that I can I show the best pictures I can take I CAN NOT be responsible for something That I DO NOT have control of So once your purchase is in the mail It is NO LONGER my responsibility Request Shipping Insurance I need Payment within 5 days from the date of purchase or I will assume you died, And I will have to file a claim with eBay to get my credit back. I accept Paypal ONLY. All items are carefully packaged and shipped via United States Postal Service (USPS). We ship Tuesday thru Friday (excluding holidays), I am a Lupus Survivor If I have any appointments that day, or a flare, I will not be able to ship, but I do ship asap, I donâe(tm)t like stuff that belongs to somebody else setting on my shelf, I like it to be moved on out. If it is breakable, I do require Shipping Insurance. Sometimes to get an item shipped to another country is expensive, sometimes I can use a flat rate, and sometimes I can not, but you are already getting a bargain. I do not feel like I should take the money out of my pocket to pay for shipping. So like I say, I try to get the shipping as cheap as possible, and if the shipping calculator gives you a price that you believe is unreasonable, please email me and I will see if it is correct or not, because in a few cases I have been able to use the flat rate package, then in some other cases, the shipping was way off, so if you have questions, just ask. Any problems or questions about my S&H charges, please feel free to contact me. I am always happy to discuss them and adjust if necessary and appropriate. Just donâe(tm)t wait until the day of the auction, please ask way before the end, if possible!!!!!
