Yesterday, I wanted to have a meeting with my accountant and was in a different city. So, I decided to sign up for WebEx's pay-per-use plan so that we could both look at my QuickBooks (it's got a variety of security features so I wasn't worried about someone hacking in).
The pay-per-use page says "Sign up today and begin using WebEx Pay-Per-Use for just 33¢ per minute!" This is an exact quote; I just cut and pasted the text here. Imagine my surprise when the receipt arrived by email and saw an overcharge -- twice the price I expected. When I called WebEx customer service, they weren't surprised at all...they get this call a lot. They directed me to something in the FAQ page that explains that the charge is 33 cents per user.
So, I went back and looked at the website and, no, there's not a little asterisk next to the big blue "33¢ per minute" headline. And, no, there's not small type anywhere on the page explaining the per user angle. And, no, it's not in the terms of service page. And, no, there's no reference to this on the page where you schedule the meeting.
WebEx is now owned by Cisco, a big company, with big firm lawyers. So, I'm assuming that this is either a terrible oversight or that California (location of WebEx's corporate headquarters) has some very funny consumer protection laws. In most places in the US, the price has to be stated in a way that has no hidden charges. Since there's no such thing as a meeting with only one person, the real minimum price is 66¢ per minute (for a meeting of two).
My recommendation: Change that Web page immediately.
Follow-up: Here's the link for the pay-per-use page. You can check and see if they've changed it.
