Excellent service
Previously I'd tried to buy Metro tickets on the Eurostar but when I did, they only had two left when I wanted four. This time I found HelloParis! sold carnets. I ordered them on the Monday and they were delivered next day, very good service.
It's a bit more expensive but well worth it in terms of convenience.
