Good point, but credit card companies hate people like you and will damage your credit rating if they get a chance.
Haven't found it the case, both my husband and I have Credit scores above 800 and we've been doing this for years. I figure if they don't like the way I use the "credit cards" then they can quit sending me the offers at anytime.
You are exactly correct!
I've seen my credit score tumble nearly 100 points in a year because I flipped a couple of balances to a "Zero-interest" deal.
BTW, I've NEVER been late on a payment.
