Thank you for your reply. Yes, I'm definitely looking forward to shopping at the airport on the way back to the US and have always declared items.
I was just wondering since France and Italy are within the EU, are the flights considered domestic or international? Are there duty free shops at the CDG terminal if I'm flying from France to Italy? If yes, will the shops let you purchase but you have to pay the VAT since you are flying within the EU but not out of the EU?
And if you pay VAT at the airport store, then will they give you the VAT refund form? (to be processed at the airport of your last destination in the EU)
Thank you in advance!
