For the buyers with multiple items that want to combine shipments, please wait for my invoice with the corrected shipment charges before paying. 
Once you pay for an item, that item will be shipped separately, not combined.

Domestic Stamps purchases:
From 1 to 3 ounces or up to US $20, the item/items will be shipped in a Standard eBay envelope through the United States Postal Service. The charges will be $2.50 for the first item and 0.50 cents for any additional items.

For invoices over 3 ounces or US $20, the item will be shipped as a USPS Ground Advantage at a charge of US $6.50 to 9.50, not including collections or lots. Any additional items will be charged at 0.50 per item.
Collections, Sheets, Magazines, Books, Coins, and other items will be priced individually according to weight and size. We recommend purchasing additional insurance for items on invoices totaling US $ 100.

International Shipments:
1.) For orders from US $ 0 to 19.99, you can select to ship through USPS International Mail Letter at a charge of US $ 6.00 for the first item. Any additional items will be charged at 0.50 per item.
(By selecting USPS First Class Mail International Letter charges without a tracking number, you will hold this seller harmless in case specific to any losses incurred during the shipping and handling from the USPS. If you disagree, please let me know, and I will gladly change the mailing charges to a method with a trackable number.)
2.) For orders over US $20.00, we use exclusively eBay International Shipping to handle shipments to any International Destination. Orders mailed through eBay International Shipping cannot be combined; sorry, this is an eBay rule.
We recommend purchasing additional insurance for items on invoices totaling US $ 100.

Payment:
We accept payments through eBay only. All invoices must be settled within five (5) days from purchase. If not paid, the order will be canceled, all items will be returned to the auction, and you will be reported as non-payment.
