cheapest way to get from High St Buckhurst Hill to Stansted

have you investigated National Express - they do Stanstead by coach and train. It seems they service stratford Tube station which is on the line from Buckhurst hill. (I found this on Google)

I try to do things simply. Buckhurst Hill (never heard of it, used Google maps) appears to have an Underground station called Buckhurst Hill. Its on the Central Line. Me, I'd consider taking the Underground to Liverpool Street station (9 stops) and taking the Stansted Express train from there. May be more miles but it should be pretty straightforward.

Thanks. I want to do it the cheapest way and the bus does not seem to go near there. I will try the way you suggested.
