By cons I've tested for the first time on amazon return: Nickel!
Delivery 04/07, as the day to return, immediate receipt of an e-mail with the link to the colissimo free return. Sending parcels received the 05/07 Friday, 07/06 from amazon. On Monday, 07.09 refund processing file, the 11/07 CB refund my account. Treatment of my perfect record, but disappointed with my purchase very pleased with amazon.
