@hawkeye10,
I don't disagree at all, hawk, with your thesis. It was a sweet deal for me. As much as a 30 day or so "float" between the time I made the purchase and when I had to make payment. No interest and a 1% rebate. It makes absolutely no sense. They were losing money having me as a customer.
One of my employees is up to his eyeballs in credit card debt. He and his lady are about 25. They pay the minimum each month and things are fine. I, and some of his coworkers, feel like strangling him. You will never get out of the hole you are in paying the minimum. The new law, as I understand it, will require the credit card companies to disclose, in something other than fine print, how long it will take and how much it will cost in interest.
Which leads me to this rant in an already too long post. I am stunned by how many folks come into my store and pick up an item costing $10 marked down by 50% and say "So how much will it cost? I was never any good at math." That is, to me, down right scary. Sheep, being fleeced.
