Hello, I can´t find a extension that can show a "Free Returns" text or image in the cart, or in the product.
There are some stores that for example (attached image), in the cart shows a text or image with the free returns, or changes...
Do you know how to do it, a module...? To show in carts more than X euros.

Hello @Espamoto
You can use the Widget to achieve this.
Follow the steps given below.
1. Create a static block (e.g "free_return_message").
2. Navigate to Admin Panel > Content > Widget > Add New Widget.
3. Select "CMS Static Block" in Type section.
4. Select your theme in the Design Theme section.
5. Click Continue.
6. Enter your Widget Title.
7. Select Store Views.
8. Enter Sort Order (e.g. 10)
9. Click on Add Layout Update.
10. Select "Specified Page" in Display On section.
11. Select "Shopping Cart" in Page drop-down.
12. Select "After Page Header Top" in Container drop-down.
13. Now click on Widget Options tab given on the left side.
14. Select the static block which we created in step 1.
See this screenshot for better understanding.
