So, if you send 1 short fax/week (@ $1 for 1-4 pages), your breakeven point just buying a fax machine ($30-50 for entry level on Amazon, new) is less than a year? I work for a business that could use a low-volume faxing service, but the price needs to come down an order of magnitude.
I don’t care how much you can buy one for, I’d pay a premium to not have to have one or set it up.
