Shopping coupons are a popular strategy used by businesses to attract customers by offering discounts or special offers on products or services. Here is a basic guide to understanding shopping coupons:

**1. What are Shopping Coupons?**

Shopping coupons are tickets or documents (either physical or digital) that can be exchanged for a financial discount or rebate when purchasing a product or service.

**2. Types of Coupons:**

There are various types of coupons including manufacturer coupons (issued by the maker of a product), retailer coupons (issued by the store itself), online coupons, and coupons in magazines or newspapers. The discount provided can be either a fixed amount or a percentage off the regular price.

**3. How to Use Coupons:**

To use a physical coupon, you typically present it at the cashier during checkout. For an online coupon, you would input the coupon code into the appropriate field during the virtual checkout process.

**4. Where to Find Coupons:**

Coupons can be found in numerous places including newspapers, magazines, online websites, emails, mobile apps (like Honey, Rakuten, Ibotta), and directly on store shelves or at the customer service desk of a store.

**5. Expiry Date:**

Most coupons come with an expiration date after which they cannot be used.

**6. Restrictions:**

Many coupons carry restrictions such as "only one per purchase" or "not to be used with other offers." It's always recommended to read the fine print to understand exactly how the coupon can be used.

**7. Understanding the Lingo:**

Coupon terminology can be confusing initially. Common terms include BOGO (Buy One Get One free), MIR (Mail-In Rebate), OYNO (On Your Next Order) and certain conditions such as   one coupon per item  ,   one coupon per transaction  .

**8. Coupon Stacking:**

Some stores allow you to use multiple coupons or even combine manufacturer and store coupons to maximize savings. This practice is often called 'coupon stacking'.

**9. Fraud and Counterfeit Coupons:**

Sometimes, people create fake coupons. Using these can have serious legal implications. Always ensure that your coupons are from reputable sources.

**10. Coupon Ethics:**

Be respectful of store policies and practices. Don't clear shelves by using all your coupons at once or misuse coupons in ways that weren't intended.

Coupons, if used wisely, are a fantastic way to save money. There  s a little bit of learning to it, but with practice, you can become proficient and watch your savings grow.

Finding coupons online is relatively easy and can help you save a significant amount of money on purchases. Here are several methods you can utilize to find online coupons:

**1. Brand Websites**: Manufacturers often provide coupons directly on their websites. If you have a particular brand in mind, visit their official website to see if they have any offers or discount codes available on their 'Promotions' or 'Offers' page.

**2. Online Retailer Websites**: E-commerce websites like Amazon, eBay, or Walmart frequently offer discount codes on their website. Be sure to check out the 'Deals' or 'Sales' sections on these sites.

**3. Email Newsletters**: Signing up for a company's newsletter or becoming a member of their website often leads to receiving coupons directly in your inbox. 

**4. Coupon Websites**: Sites like RetailMeNot, Coupons.com, and Groupon collect and provide coupons for a wide variety of retailers. 

**5. Social Media**: Many companies announce special deals or coupons on their social media handles. Follow and keep track of your favorite brands on Facebook, Twitter, Instagram, or other social platforms to access these discounts.

**6. Browser Extensions**: Extensions like Honey or Rakuten automatically apply the best coupon code they find to your order once you're at the checkout page.

**7. Cashback Websites**: Sites like Rakuten and Swagbucks not only provide cashback for making purchases from partnering brands but also provide coupons and discounts. 

**8. Online Forums**: Websites like Reddit have threads (e.g., r/coupons) where users share coupons and tips about finding and using coupons.

**9. Mobile Apps**: Some mobile apps like SnipSnap and Coupon Sherpa are specifically designed to find and provide coupons.

**10. Online Surveys/Paid Websites**: Some websites offer coupons or gift cards in return for completing surveys or signing up for trials.

Remember to check all the details of the coupon before using it to ensure it's valid for your intended purchase. And remember - while coupons can save money, they should be used wisely to ensure sensible spending.
