Paris and London have a long and well-documented relationship. If you're in one of the two cities, it only makes sense to visit the other while you're "in the area." But not everybody can afford tickets on the high-speed Eurostar trains. Though Eurostar does have some sales throughout the year, you can get an even more affordable round trip ticket between Paris and London any day of the year with iDBUS bus services.
iDBUS' frequent daily voyages and user-friendly site makes it super-easy to book a cheap ticket between cities. You can go from Paris' Bercy Station to London's Victoria Coach Station with their 39€ Mini Price! I'm not gonna lie, it is a long journey - about 8 or 9 hours - but that's a snap for overnight voyages and with your ticket you get free wi-fi, electrical sockets for your gadgets, real-time voyage updates, and you're guaranteed one free checked bag plus a carry-on.
When you sign up for the iDBUS newsletter, you'll get updates and first notice on deals between Paris and London, but I'll let you in on a deal that lasts all year round: buy 3 tickets, get one free. If you have a few friends to bring to London (or from there to Paris), go in on the deal together and save some bucks!
iDBUS also has lines to Amsterdam, Genoa, Turin and several other cities in France, so if you're looking to travel in style for cheap, especially from Paris to London, check out the site and make use of this awesome deal. Just don't forget your passport.
