When I had to fax a stack of pages, I found Office Depot to be the best deal. They charged per page, but the total came out lower than FedEx or USPS. The staff even gave me a quick tip on formatting so everything scanned properly. I actually found out about their rates through , which lists up-to-date fax prices and options. If you’re faxing a lot, bring your pages ready and ask if they can scan double-sided — that sometimes cuts costs.
