<prompt> Human: I currently pay all my monthly expenses mortgage, utilities, cell phones, etc within the first week of the month. In other words, im up to date on my bills. Is it a smart move to open an American Express account and use it to pay all my monthly bills? as long as i pay off the balance every month, it will strengthen my credit, yes? is this a smart move? let me know your opinions, PF!Thanks!  <response>: My American Express Blue Cash Preferred card offers: Cash back at the rate of 6 at grocery stores up to 6000 per year, and you can purchase gift cards for other stores if you dont normally spend 6k a year on groceries which allows you to cheat the system. I will often buy Amazon.com cards at the grocery store, but obviously there are dozens of stores to choose from. 3 at gas stations. 3 at major retail outlets Macys, JC Penny, Bloomingdales, Boscovs, Kohls, Lord Taylor, Nordstrom, Sears, and many others. 1 on everything else. Varying coupons like spend 50 at JC Penny and get 10 back, spend 15 at Amazon get 15 back, 10 off a 10 purchase at walmart, 5 off a 5 purchase from itunesapp store, I have used all of these personally that vary with time. There are usually close to 100 of these going on at one time that are good for 1-3 month periods. An extended 1 year warranty on top of manufactures warranty. Extended 90 day return policy on all purchases. Your eligible purchases can be covered when theyre accidentally damaged or stolen for up to 90 days from the date of purchase with your Card. Other miscellaneous Bonuses. Free rental car insurance. Free 2 day shipping and free return shipping at 80 online retail stores through ShopRunner 80 per year normally. A free yearly FICO score. And perhaps the most important thing of all,... among the best customer satisfaction of all the credit card companies . Last tidbit is a story I would like to share. I was in Dallas, rented a car, apparently they have toll roads with no toll booths not sure how a non-local would even pay the toll. Got a 17 charge from some company in Arizona which I did not recognize. Reported it to Amex as not authorized and they reversed the charges. I later found out that it was for the unmarked toll I guess they use some kind of out-of-state billing company. So Amex gives you free tolls on rental cars Joke,... but not really.There is an annual fee of 75 but you get 150 as soon as you spend 1,000 in the first 3 months.
