I got an Amazon "store card" -- just FYI it comes with a 40 dollar gift card and has no fees etc so it's free money. I'll never use it but it does come with 5 percent off Amazon purchases and it attaches automatically to your account, so it's kinda handy as long as you remember to pay it.
I'm actually holding off on opening a Charles Schwab bank account because they require a link brokerage account which makes a hard credit pull. Mine's not bad, but if I'm going to make another hard pull I'm going to get my balances down a little more first. Pity, cuz PNC is sucking out $15/month right now, those vampires. It's good to know, though I have to be annoying and point out that whenever a company makes a hard pull on your credit score they're required to disclose this and obtain your consent for the pull prior to doing so, it's a part of the Fair Credit Reporting Act (FCRA) - I've done my fair share of FCRA compliance reviews, though, so I'm biased. I know way too much about banking.
Oh I'm aware. I'm buying a damn house. FCRA is on my radar. What amazon did was dress the "store card" up as closer to a gift card than a credit card (it's absolutely closer to a limited debit card...) and bury the check in the fine print. Ah well. My cred's fine.
Mine is a standard credit card that rewards me with Amazon points. I use it for everything and pay it off in full every month. I paid no fees or interest on this card in 2015, but made very close to $800 in cash back. My CC has a rate of 12% (started about 20%) and I look at this as a way to pay for my literature addiction.
Debt is a tool, and like any tool, when misused it can destroy your life. Learning to manage debt is about as critical a life skill as any. Use a no-fee or low-fee card that gives the rewards that will best help you in your goals and use that card, pay it off in full every month, etc. Easy to say, hard to do.
