The product I bought (Tribord snorkelling mask) was brilliant but when I first tried to order online they were out of stock. I selected to be notified when the item was back in stock but unfortunately I never heard anything and luckily checked the website again and found they were back in stock, almost 2 months later. I don't blame Decathlon for not having the stock as I was aware there was a supply problem with the manufacturer (they themselves were out of stock for months) but I don't see the point in asking customers if they wish to be informed when the item is back in stock if they're never going to bother contacting you!
