I hear in commercials "Call for your free quote" as if anyone would pay for a free quote which is essentially a sales proposal. Sometimes I feel like calling and asking about their normal rate for a quote and asking them why they are free now. Then again I like to ask telemarketers off beat questions. Hit reply for your free opportunity to reply!!
Free?? Are you sure? Ok then... my favourite one is "call now and you'll also get this free ******, but hurry this offer is only available if you call within the next 30 minutes". And then the same ad is repeated every 30 minutes.
