I used CDiscount to buy a few items, and I found them good although I have heard that when customer support is needed, they are non existent. They had a flat rate shipping fee to my country (so I knew what the overall price would be) and it was possible to filter results when searching for something, by the sellers or products that would ship to any country, but that option has been removed since January and i have no idea how to contact them to find out if it will be coming back. Bad timing it seems, as they could’ve taken a few customers from amazon until that was removed.
