You’re giving away too much for grocery deals

Each swipe of your loyalty card, keypad entry of your phone number, or submission of your email address tells the store everything you bought, when you bought it, in what quantity and at what price, along with your payment details.

And guess what? All that info goes to third parties they share the data with too. Try one of these methods instead:

◾ Use your office phone number as your loyalty number. If the store needs an email address, give a disposable one.

◾ Look for stores that don’t require loyalty programs for discounts, like Trader Joe’s, Walmart and Target.

◾ Most grocery stores have a coupon section on their website where you can print, snip and hand in paper coupons.

◾ Whatever you do, never give your Social Security number or driver’s license number.

◾ Ask for the discount anyway. Cashiers usually have a code to charge the digital price without belonging to their loyalty program.

◾ If all else fails, smile politely and ask the person behind you, “Hey, mind if I use your card?”

Smart news go-around

Have a friend who shares articles from Apple News or another aggregator? Sometimes, you can’t open them or get a paywall from Apple.

Here’s a workaround: Do a Google search for the title. You’ll almost always find it free to read on the original site.

Google pro tip: Search tricks to get what you want

Tech you can’t toss in the trash

There are certain tech items you can’t put in your recycle bin or trash can. Doing so is illegal in some places. Here are the proper ways to handle them:

◾ Batteries, especially lithium-ion and nickel-cadmium types, should be taken to a hazardous waste collection center.

◾ Your television is packed with glass, lead and potentially hazardous materials, and it’s not meant for the landfill.

◾ Let's not forget relics like those old glass thermometers. If you still have one, it likely contains mercury. Don't toss it in the trash, and whatever you do, try not to break it.

If you need to eliminate any of the above, search online for your city or town’s name plus the term “electronics disposal.”

Quick way to speed up your phone

You can have as many tabs open as you want on your Safari browser or Google Chrome. Chances are, you have hundreds open. It’s easy to clear them out, and you really should every now and then.

◾ On iPhone: Open Safari, then press the two overlapping squares icon. When the pop-up appears, select Close All Tabs.

◾ On Android: If you're a Chrome user, just say, "Hey, Google, close all tabs.”

Gas tank trick

You pull into a gas station, and, whoops, the tank is on the other side. Here’s a little trick so you never mess it up again, even in a rental or if you borrow someone else’s car. Note: This doesn’t apply to every model, but most have it.

◾ Look at your car's fuel gauge on the dashboard. See the small gas pump symbol? Right next to it is a tiny arrow – it points to the side of your car where the gas tank is.

The tank is on the car’s right side if the arrow points right. If the arrow points left, the tank is on the left side. Voila!
