Is Efax a viable cost savings

I use myfax.com for 10 bucks a month.

You'll still need some way to scan documents into your computer to use any sort of online faxing service.

The best feature for me is being able to receive a fax wherever you are instead of having to go where the fax machine is located.

Also convenient for forwarding faxes on to clients delivering a much clearer and cleaner copy.
