We use our best buy credit card for our daily needs and to pay our bills. Water, electric, gas, dining, you name it. What? The interest rate, you ask? I don't care what it is. The card never carries a balance. We pay off our card every month. By doing this, we earn a LOT of rewards. I earn triple points for using the card to pay for my cell phone bill. I think that promo is now over.
I use those rewards to get items from Best Buy for free. This includes my ink and paper for printing coupons. Technically, I spent money to make money. The difference is, the money spent on the card is money I would've spent in cash anyway. So why not make your money earn you free stuff? The trick, don't spend more than what you can pay off in one month. In other words, don't get reckless.
I usually shop in the clearance sections or for items on sale. I also buy stuff we actually use and not just crap. If something I did get was a dud (pink hello kitty ipad case), it doesn't hurt too much. Cause I paid almost nothing for it.
Here's my proof below. I also write reviews on everything I buy. Of everything you see listed below, the only thing that sucked was that pink hello kitty case. DON'T GET IT. When you turn the ipad on its side to watch movies, that case (for some odd reason) makes the ipad shut off and the screen goes black. It's super cute and props up nicely, but that one flaw makes it utterly useless.
