I've received my online order and would like to return it?

Online orders can be returned as standard via the method listed here https://www.decathlon.ie/en/content/8-365-days-return using An Post and this is for a refund only.

The exchange of online orders for different sizes or alternative products is not possible via this method and can only be done in store where a refund can also be chosen

You would just need to bring a copy of your orders invoice with you to the store with the unused/unworn item and the in store team will be able process a refund or exchange if chosen.
