Second what Moriarty said about Ser Jacopo's. With the Euro declining in relation to the dollar, and Italy in the throes of a major recession (means a weaker domestic market for pipes), the situation is going to be even more advantageous for price sensitive US buyers. And not just for Ser Jacopo's. I know an eBay seller ID that is in reality used by an Italian shop owner who has no other visible online presence. He put a brand spanking new G Sea Rock in a very desirable shape on auction - 99 cent open, no reserve, no buy it now - that closed about $30 under what a US dealer's cost would be (about 45% of US MSRP). Many brand new Italian pipes are on eBay from reputable shops, and if you know what you are doing, you can figure out the shops real identity and buy them even cheaper directly. For example, there is a gorgeous Castello old Antiquari in an unusual shape with delicious silver work listed on eBay at a buy it now price of $495, a screaming bargain. That same dealer lists it direct at about $405 after currency conversion and VAT rebate. (Customs will run you about $12). If there is a best offer option, don't be bashful, start off at at least a 40% discount. And you should at least get the VAT back, if you are in the US. (20%, but part of that is supposedly non refundable, so it works out to about15%).
This has happened before, back in the 90's when Italy was on the lira. These are retail merchants with excess inventory. Their currency is weak compared to the dollar. They are used to handling VAT rebates and express shipping is cheap. All of this is a lot easier than it used to be. Conduct yourself accordingly.
