Founderscard gives you a lot of benefits. From cheaper rates for rental cars, hotels and airlines and benefits in the categories travel, business, hotels and lifestyle. They also have great events all over the globe. With the membership you get complimentary access to this events.
The usual rate is $795 per year, with my promocode FCPETER861 you get the annual membership fee for $395. For me that pays off usually after the first flight or rental car I book. Every subsequent booking is just added money in my pocket.
Any questions about Founderscard, feel free to contact me.
