We had a great vacation - London, Paris, Venice, Florence, and Rome in three weeks! We are finally leaving for home (California) and wanted to check with you experienced travelers if there's anything we need to know regarding customs. We did make a few purchases so do we claim them all? Or just ones where we received a tax free document? When we where In Murano, we purchased some glass art and is being shipped to our homes - we won't have them at hand (of course), but do we need to claim them too? We where given sealed envelopes with our receipt and documents of authenticity. We were also thinking of picking up wine at a duty free shop at the airport. Good idea? We just carry them on. Most of our purchases were souvenir items - inexpensive items for our families.
Also, we are changing planes at Heathrow, does this make any difference?
