I'm curious if you've managed to find an insurance company that does not use credit score as a factor in their premiums? If you've found one, I'd love to know who they are. All of the ones I spoke with use credit score in determining rates, and my understanding is that's standard here in the U.S.. If you know of one that doesn't that would be incredibly beneficial info to those who wish to avoid playing the credit score game.
I both earn and save money by playing the stupid silly credit card game, which is my primary motivation to do it. I posted one example
here. I avoid getting any cards that have an annual fee and I do not pay interest. I coordinate the new card bonuses (e.g. $100 bonus to spend $500 in the first three months) with necessary big ticket purchases such as a year's worth of auto insurance at once, which purchasing in one lump sum gives a discount, and then earns me money as well. Free Shoprunner (2-day shipping) and
extended warranty on items purchased through my credit card--
including theft protection of said items--are additional perks that make it a no-brainer decision for me personally.
All that is in addition to the cash-back perks, which may be negligible but do add up over time if you're spending it on purchases you already need. As much as 5% cash back. And, the better your score, the better offers are open to you. $500 bonuses just for getting a card and using it a few times do happen. Easy money, IMO!
Finally, SSI doesn't let me save. If ever my total accounts go over $2000, income ceases until they are back under. I can technically save in cash under the table, but about 95% of transactions occur online for me, plus making a deposit doesn't work because then they want a paper trail for how I came across that money. (Saying it was a gift is no help--they will decrease my income by the exact amount of the gift.) So credit is also used as savings to me, and if I'm having very lean times then I buckle down to pay it off, always making the majority of purchases on a no-interest card in case I have more unexpected emergencies than the card can handle. This is something I absolutely detest about SSI and one reason I'm trying so hard to get off it--I want the freedom to save up an emergency fund, dammit!
I understand those who wish to opt out of the silly game entirely, but I strongly disagree that being in debt is the only reason for having a credit card. For me there are a multitude of benefits that very much outweigh the hassle involved. But, to each their own.
