I never was able to use my advertised points except once for some gas cards through AT&T Universal. That was really the only decent card that I had, but I believe that it changed at some point to another company.
*Hack* Well after STRUGGLING for YEARS to pay off debt I began to rack up while in college...you know, the part that begins with small limit, no fee, low percentage, no annual fee cards that quickly become monsters that eat all your salary making you earn less than you did when you just earned minimum wage...I now only carry a debit card from my local bank. It's cash only. I have considered getting a genuine credit card again, but likely won't until there is a some sort of credit slave's bill of rights like proposed by Obama/Biden in the present war on terror...I mean presidential campaign. LOL! Just kidding. But truthfully, I am one of the victims of the ever moving adjustable interest rates, nightmarish fees without any checks and regulated balances, and even credit repayment agreements where my terms changed there as well! I've sent payments in early and been charged late fees AND had MY INTEREST RATES raised to 30% default rates on ALL MY CREDIT CARDS because A CREDIT CARD COMPANY had my payment in their MAIL ROOM! AND THAT's NO LIE or exaggeration! They took the fees off and reduced the interest on the card in question when I complained and proved that they cashed the check BEFORE the due date, but then they did not reduce the rates on the other cards, they added the fee back on the card 3 months later and I continued to wrestle with issues such as this the entire time I owed thousands of dollars to them. NEVER, NEVER go into any significant debt to credit companies, never take out the insurance that really only protects them, and NEVER file bankruptcy that really only helps them out (I didn't do that...didn't have to, but know people who have...credit cards are UNSECURED debt...meaning THEY take the risk of loaning the money.).
