Because the holiday season has arrived and many people are already in the shopping mood, Google has released some new eCommerce features; I’m sharing this one in case you missed it: the new “coupon and promotion labels”.
Copy & Paste Coupons Directly From Search

How Does This eCommerce Coupon System Work?
It’s worth noting that this only affects Google Merchant Center.
Coupon codes are a great way to save money, but finding them and verifying that they work can be difficult. We, for example, place promotions front and center in product searches to help shoppers save money and time.
Many websites provide coupon codes, which you can usually find by searching for the website name and the word “coupon code.”
For those who don’t know, in the United States, Cyber Monday is a marketing term for the Monday following Thanksgiving. Marketing firms coined the term “Cyber Monday” to encourage people to shop online. Cyber Monday is a day when people can buy items that are either unavailable in stores or only available online. Cyber Monday is a good day to find bargains because many retailers offer special deals and discounts.
Black Friday is the day following Thanksgiving Day. It is a busy shopping day that marks the start of the Christmas shopping season. Although Black Friday is not an official holiday, many non-retail employees have the day off because it is a school holiday for the majority of students.
