You must present the sales receipt when requesting a refund. For exchanges, the sales receipt is optional, provided that the following rules be complied with:
- a vintage product can be exchanged if there isn’t more than a one-year difference between the vintage being brought back and the one currently being sold;
- the label must not have changed;
- a product with an expiry date must not be expired;
- the product must exist in the directory;
To be exchanged or reimbursed, the returned product must be sealed in order for the store to be able to sell the product again, and the product inside the container must be defective. In this case, the returned bottle must be at least three quarters full. Otherwise, the packaging, the bottle and the labels of a sealed product that be can be sold again must be in good condition. An open bottle that doesn't have any fabrication defect cannot be refunded or exchanged.
With or without a sales receipt, a product that can't be consumed due to a fabrication defect can be exchanged or reimbursed under certain conditions. The bottle of a defective product must be at least three quarters full.
