Can someone explain to me the VAT refund process at CDG? We are flying CDG/PHL on US tomorrow. My previous experience with this process in other countries is that you handle this procedure after you check-in and pass security so you have to carry on your purchases. However, they rarely look at them (in TLV they didn't even look at all).

However, I have read some information where it indicates that you present your purchases to customs at CDG before you check in for your flight? Is this correct? Do they look at the stuff or can I pack it without having to worry about pulling it out of our bags so long as I have the refund forms and receipts?

Thanks.
