I need to receive faxes, but don't want to purchase a fax machine. Ideally, I would like to receive the faxes by email. Does anyone know of a good, relatively inexpensive service for receiving faxes by email?
Check out http://www.efax.com . You can get a free recieve-only fax number from them, that receives faxes for you and sends them to your email address. The catch is that it's probably going to be a long-distance number. Meaning that if you wanted a local store to fax you a price quote, the store would have to dial a long-distance number. My free eFax number is in California, and I live in New Mexico.
You can also subscribe to their EFax Plus service and get a local fax number from which you can both send and receive faxes from your email.
http://www.callwave.com has a good fax service.
