If you are wanting to exchange, simply bring your item/s to the store, with the email address registered to the Decathlon account, which the items were purchased on, and our friendly teammates will be able to handle the rest.
If the item you are replacing with the original purchase costs less, then the cost difference will be refunded in the same form that the original purchase was made, be it to the same credit or debit card, in cash, or onto a gift card.
Inversely, if the item you're hoping to exchange your product for is more expensive than the original purchase, you will be required to pay the difference.
If the original credit card is not on-hand, then the difference will be loaded onto a gift card instead. We will not refund the difference in cash or onto an alternate credit card.
