We're getting business cards printed for Postica so we decided to get a toll-free number to put on them. It will be good to have on the web site too, since we currently just have our support email address.
A search on Google for 800 number or toll-free number brings up a ton of ads. We went with GotVMail because the price is good and we were able to sign up online in about 10 minutes. We didn't have to talk to a salesperson or fax any forms like other companies require. We're paying $9.95/month plus 7.4 cents/minute. If we start getting a lot of calls, we can start buying blocks of minutes for about 5 cents/minute.
The state is that great fiction by which everyone tries to live at the expense of everyone else. - Frederic Bastiat
