A viral TikTok trend is helping people save money. Creator @averagesisi loves to shop online, but discovered that saving can be just as fun. Here’s what she does: when you find something you like, put the item date and price in your notes. Keep track of all the items you want, take some time and if you don’t make the purchase keep it in notes. At the end of the month, add up the total in notes and put half in savings. Financial experts have been touting this method for years.
