Yes that was a concern of mine (the invoice) and since I have not sold anything on here as of yet I dont know how the invoicing works, if you can adjust it prior to sending, or if it is automatically generated. We sell alot of larger items to Austrailia and I think 39 inches is the maximum length with USPS. Most of the buyers there know that and request we ship it to a shipper in California and opt for the shipping cost in the lower 48 states. The main issue is for them to be able to see the listings/auctions.
