I've used Decathlon both for mail order and over the counter in their store in Barcelona. As for the service and products in Barcelona I can only say top class from the staff dealing with my queries, buying great goods at such value and the shop's location. As for buying the Easybreath mask the service was great both on the original order and getting the replacement after a fault developed. The only problem I've with Decathlon is that they don't distribute directly to the Republic of Ireland ???????? by mail order and your sales would go through the roof if so. ???????????????????????
