For domestic shipping, if you purchase multiple items we will ship together and charge actual shipping.  International shipping requires one item per shipment.  If ebay gives you a crazy cost for shipping, please send your shipping address to me so I can confirm and possibly get a lower price.  
Return Policy:
If we somehow messed up and did not accurately describe the listing, we will certainly accept a return and pay for return shipping.  However, please make sure that this is what you want.   All returned items must be in the same condition as when shipped.   If you can think of any reason that you may need to return this item, please contact us to discuss before you bid or purchase.  If this item is returned for any reason other than incorrect listing, shipping will not be refunded.

Notice:  Tamper Evident Serial Number label:
To facilitate record management and returns, we may apply a serialized, temporary label to the item.  These tamper evident labels are easily removed but we will not accept any item returned without this label or if the label has been removed and reapplied making its ‘tamper’ indication appear.  When you are certain that you are satisfied and will not be returning the item, the label easily peels off without leaving any residue.
Thank you
