All packaging fees are included in the shipping costs. Returns are only accepted if an item has a significant error from auction description. Please ask questions before bidding, thanks for looking and good luck to all. International bidders: To significantly save you $ on shipping costs I do not opt to participate in eBay’s Global Shipping Program for sellers which can almost double shipping costs and may delay delivery time for buyers. However, an auction listing error may slip by me from time to time. Please advise if overseas shipping appears excessive. I do ship globally for most items, items must be packaged and weighed prior to shipping quote. All shipping quotes are firm and will not be subject to change or refund.
