@Leea, Thanks for the heads-up on DHL. I'll keep that in mind.
I went to the UPS online shipping calculator and was surprised to find the rates very reasonable, in the $300-$400 range. If that holds true, that would be great. I called UPS today to get more information on the paperwork requirements to export and they provided me with a Commercial Invoice form to fill out and an example of a completed Invoice. About the only piece of information I'm missing at this point is the retailer's VAT number, which I have requested. Once I process the shipping order and have the tracking number I can start on the SAD form (Single Administrative Document). The SAD seems to be much the same information as what is on the Commercial Invoice so I should have a head start on that.
I was able to have the retailer send me a link to pay with my credit card. I pushed for that after I discovered that they do not have the frame in their possession. Supposedly it is at the distributer's warehouse. This retailer has what appears to be a good presence in multiple countries in Europe so what would be a red flag is orange-ish at this point. I processed the payment to reserve the frame and have crossed my fingers that they can produce it. Of course, they said that if there were any issues they would refund me. I have a lot of emails to forward off to the credit card company if I need to start a case, but my gut tells me I'm okay here. Time will tell.
