Although, I'm sure that some people prefer the door-to-door method, I know that I, personally, will never buy something from a person walking up to my door — yet I have done it over the phone. Whether this is a psychological block or human nature, I can't say — I do think that it has to do with the product of society. In the 50's and 60's, it may have been reasonable to expect someone to open the door for you and let you in to demonstrate the product. I can't imagine that this is a reasonable expectation in today's society.
Citibank, however, seems to have decided that going door to door is a valid choice. As posted in "Seth's Blog: Not what it used to be" back in November of 2005, "an assistant Vice President at Citibank. He's wandering the halls, door by door, trying to sell business checking accounts." I think that they would have had more success telemarketing, but I suppose you can be the judgement of that — have you seen many Citibank sales people at your business door lately? How about telephone calls?
I thought so!
