Once I know what I'm doing, I prefer online. But when I do something for the first time, I usually need hand-holding to answer the silly kinds of questions newbies have and get me through the details. What I don't like about phone trees is determining which category my question falls in. I call only when I can't find the answer online. Instead of trying to figure out whether I need to press 2 or 3, for example, I just wait for an operator to come on the line.
When I was doing my door-to-door training (the Cutco knife division of WearEver Aluminum in those days), the sales manager told us if he didn't speak to the car sales person for at least 2 hours, he knew he paid too much. I went to the store to buy a vacuum cleaner back then and I felt cheated when the sales person didn't try to sell me on one particular model over another (nor did she ask me qualifying questions about why I needed a vacuum cleaner). Instead, she pointed to a wall with half a dozen models on display and asked me which one I wanted to buy.
I hate to haggle or make trade-off decisions about which model and options I want (I usually default to the lowest price when faced with a decision to make). The reason I bought a Saturn many years ago is the no-haggle guarantee. Here's the price, take it or leave it. Henry Ford was on to something when he said you could have any color you wanted as long as it was black.
I love it when my landlord says the rent is due on the first of the month and late fees kick in on the fifth of the month (no exceptions for weekends or holidays). I have a stake I can drive in the ground for planning the rest of my life around. I never have a conflict with my rent payment. If I happened to be short on cash (which I'm not anymore), it's my other expenses that would have the conflict.
