After shopping at H in Paris, I understand the detax forms are filled at the store and I have to get them stamped before departure and mail them back. My last stop in europe is actually Amsterdam. After getting the forms stamped at the airport, should I : a) wait till I get home before mailing the forms back to Hermes Paris (I've no time to mail in amsterdam airport ) or b) get my money back from the 'Tax Refund' booths at the airport? If mailing back to Hermes Paris, does the rebate come back on my credit card? I hope those who have been through this before can give me some advice. Thanks very much!
