In 2020, I learned how to coupon through TikTok videos. My CVS app says I've saved over $2,000 in the last five years by couponing. I can save money with relatively low effort. When I was furloughed and pregnant in 2020, I, like many others, was addicted to TikTok. However, I wasn't on the app watching teenagers dance. I was learning how to coupon. Because I could really only go to the grocery store or drug store during this time, couponing became a way to save money and entertain myself.Five years later, I'm proud to say that my frugal ways have helped my family save a ton of money in grocery and household costs. According to my CVS app, I've saved $2,322 in the last five years and that's just at one store. I haven't paid for toothpaste in years and had a good couple of yearslong streak where I never paid more than $1 a gallon for oat milk.It's social for me, too; my neighborhood group text is always buzzing with advice on what deals were good this week. With steep prices these days, couponing is an essential and easy way for me to keep costs down and have a little fun gaming the system. Here's how I do it.Most coupons are digitalSome people have an image in their heads of a mom in the 90s with a big coupon binder. Times have evolved; all my couponing is done in-store apps and a few external aggregate apps. I have two small children, so while I'd love to get organized and go through each store app and plan my trip out, most of the time, I'm shuffling through the deals and adding them quickly to my queue as I walk into the grocery store with my girls in tow. I've only reached for a handful of paper coupons in the last five years.Many apps now have a scan function, which allows you to scan a barcode on an item and see if a coupon is attached to it. Coupons either come off during the transaction, such as in a store app like Kroger or Publix or after you scan a receipt, such as with Fetch and Ibotta. For these, funds can be withdrawn at any time directly to your bank account.To make it even easier, coupon influencers can guide you through coupons for stores such as Target, Dollar General, and even Sam's Club. They regularly highlight deals for name brands such as Bounty, Pampers, Arm & Hammer, and Rubbermaid.Coupons exist for lots of categories of products, including premium groceriesCoupons can get you great deals on everyday items like canned goods, yogurt, and cheese, but premium brands give out way more coupons than people might think.Merryfield, for example, is a couponing app with coupons for expensive brands like Applegate Farms, Vital Farms and Lesser Evil. I regularly see coupons for Siete and Dave's Killer Bread on Ibotta; I've gotten free Wow Bao buns from the app Aisle that retail for $8.79 at Kroger. I've even used coupons from some of these apps at Costco and Trader Joe's. If you love Sumo mandarin oranges, you'll know they can cost up to $6 a pound. There's a current coupon for them.These cost savings add up in a major way with relatively little effortEvery time I tell someone I'm a couponer, they scoff that it's too much work to keep up with, but to me, spending a few minutes each shop doing the work is absolutely worth it. I'm saving money and getting a huge dopamine hit. I squeal with glee when I work a good deal, begging my husband to ask how much I paid for something. (The answer is often that I was paid to take the item from the store, a regular occurrence at my local CVS where I go so often they greet me by name.)While free stuff is amazing, the real value is in the little coupons that accumulate over time. If you combine this strategy with shopping your store's weekly sales, the savings can be enormous. In today's economy, every cent counts, and coupons are a proven way to make your money go even further.
