<shudder> 1-900 numbers. So they give you a number to order something from their catalog, but not only will they get money from you for the items, it's also $1.50 per minute for the call. "I'm sorry sir, but our systems are running a little slow today" to the point your 1-900 fees are more than the items your ordering.
No, no. It's ok. The 900 number is just to order the catalog itself. Once you get that, then you place your orders the regular way.
(Or, that's what the scumbags told themselves, I'm sure)
I think the only thing that outdoes this is the Santa Claus commercial that would play the DTMF tones for the kids who didn't know how to dial a phone. I can't find an example now, but I've seen it before, and Wikipedia has a reference to it.
