Thrifty Thinking: Credit Cards are Like Hoverboards

Credit cards are like hoverboards: popular during the holidays, helpful if used right, but with the potential to throw you off balance and leave you hurting. As as a personal finance blogger, I was wondering if you'd be interested in writing an advisory around this, especially with credit card offerings getting progressively more aggressive, and given that credit card sign-ups hit a peak in November and December? According to ValuePenguin research:

• Retail credit cards are a terrific deal — for the retailers. Yet Consumers end up signing up for these cards, lured in by in-store sales pitches. Unfortunately, most of these cards come with very low credit limits, astronomical APRs (20-30% on average) and in some cases, complex deferred interest deals that can slap consumers with hundreds of dollars in retroactive interest at a later date.
• Savvy Consumers should consider travel cards instead. Consumers can leverage their increased holiday spending to can pay for a warm-weather getaway in January or in time for Valentine’s Day with the accrued miles from their credit cards.
• Credit card bonuses actually offer more savings than store cards. For example, top cash back cards currently offer $150 when you spend $500 in 3 months from the time you open your account.  That comes out to a 30% savings - something no store card is offering at the moment. 
• Ultimately, don’t go overboard. Don’t run up the balance on your credit card just to buy a robot snowman to impress the neighbors. Use less than 30% of your available credit on your credit cards at all times and pay off your balances where possible.
