Play around with combinations of words and figure out what works for you — an alert for “flight flash sale” to keep up on airline sales, for example, or “laptop discount” if you’re looking for a deal on a new computer. The best part is that there’s really no downside to setting a few alerts. If, after a few days, you find they’re not sending you useful information, you can tweak them or eliminate them entirely.

Get TSA PreCheck or Global Entry for Free

Having Global Entry and/or TSA PreCheck is a must for frequent travelers to ease the way through those long security lines. But why pay for it? A number of credit cards out there will cover the fee ($100 for Global Entry, $85 for PreCheck; Global Entry includes the PreCheck benefit) with miles or points or, better still, cover the cost entirely by way of a statement credit.

The Altitude Reserve Visa Infinite card from U.S. Bank offers up to a $100 credit every four years for Global Entry or PreCheck. Among other cards that tout the same benefit are the Chase Sapphire Reserve card, the American Express Platinum card and the Citi Prestige card (which offers the credit every five years instead of every four years).

Money Back on Your Purchases

Make your online shopping work for you by using shopping portals — sites that get referral bonuses from retailers and then pass on some of those savings. Let’s say you want a new pair of boots for a coming trip, and you plan to purchase them from Shoes.com. By making the purchase through a shopping portal like Ebates, you could get a big chunk of that purchase refunded to you; as of this writing, Ebates is offering 12 percent cash back on purchases from Shoes.com. Money you earn through the portal is sent to you via check or PayPal.

Most of the major bank and credit card companies have their own shopping portals, too. Discover Deals is currently offering 5 percent off purchases made in the Apple Store — why not get $150 back on that $3,000 laptop purchase? Use sites like CashbackMonitor.com to track which portals are running the best deals.

No More Pesky A.T.M. Fees

A.T.M. fees can mount up quickly when you’re traveling. Fortunately, there are options. The Citibank Account Package will waive A.T.M. fees when you maintain an average $10,000 monthly balance. And Chase’s Premier Plus Checking will waive fees up to four times per month when you maintain a $15,000 monthly balance.

The king of vanquishing A.T.M. fees, however, remains Charles Schwab Bank and its High Yield Investor Checking account. The account requires no minimum to open, charges zero fees regardless of account balance and offers unlimited rebates on A.T.M. fees worldwide. The catch: It has to be linked to a Schwab brokerage account.
