1) I have been selling on ebay for over 20 years. If you have any questions feel free to contact me and I will try to get back to you as quickly as possible.
2) I will combine shipping on items that can safely be packaged together. I will send you a refund of the extra costs as soon as I package and print the shipping label. It is a quick process.
3) Shipping for this item in the U.S will be $7.00. International shipping is handled by the eBay international shipping program. I do not have a quote for you because they handle the shipping costs/process directly with the buyer.
4) I will always listen to offers, but I won't always say yes. If you are reasonable or you multiple items, I will try to make deals for my customers. It never hurts to try and I love to help out repeat customers.
