M: Did you feel like you need more hours from the day1? Well, Good Housekeeping Magazine has some advice on how you can stop wasting time and get it all done. And here with the top ten tips, is Carolyn Forte. Hey, Carolyn, good morning!
W: Good morning, Hoda. Nice to be here!
M: Your No.l tip is bank online. Some people are afraid to do it, but you say it’s something smart.
W: Yeah, it is very safe. And we certainly recommend that you use your own bank’s website. So [19]go to the bank, talk to the consumer service representatives there. It’s the best way to find out how safe it is and how easy...
M: And how much time do you think you could save, Carolyn, by doing that?
W: If you’re making transfers, or checking your statements, you can save up to an hour.
M: The second tip is online grocers. Now, that’s really not for everyone, but you actually go grocery shopping online.
W: That’s exactly what you do. If you are the type of person that wants to read every label and look at every piece of fruit, it’s probably not for you. [20]But if you wanna give up a little control, you can definitely save some time.
M: And what’s the good strategy if you decide to shop online?
W: What I would suggest is do the staples online.
M: What do they include?
W: The brands you use all the time, the paper products, the cleaning products, the cereals—get them online and go to the store for the meat in the produce.
M: That’s enlightening.
