Can we engage in commerce with Mars affordably?

Is there, within the context of presently known technology, any way of hauling passengers and cargo between Earth and Mars on an ongoing basis, at reasonable (for space travel) cost per ton?

Apart from the question as to whether any materiel's available on Mars would justify the high cost of transport back to Earth over the years landing on Mars has proved to be a very challenging problem with something like 75% of all landing attempts ending in failure.

Define 'reasonable cost'

A Space Elevator is the only prospective means of getting into space relatively cheaply.  However, while the mechanics of a Space Elevator are well understood, no known material appears to be strong enough to actually allow one to be made.  Iirc, even Carbon nanotubes are not strong enough - close, but not quite there.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

This is not looking good.
