I read that Italy has one of the highest VAT refunds in EU, but since I'm only in Paris, the cost of train tickets etc might not be worth the trip after all.
Guess I'll just bring a card with the best cash rebate to Paris!
globalblue in paris is a flat 12% off the purchase price. in italy, the AD i went to used www.taxrefund.it which offered higher VAT rebate depending on the tier of the purchase. more than 8,000 euros, you get 15% back!
Do some research and email some ADs to check and you could save an additional 1% for a michelin star lunch! ;p
P.S. group buy also have discount... my friend and I bought one rolex each, knocked the price down from 11,500 euros to 11,000 euros.
