Strikethrough is an eBay feature and is available to all Store subscribers through Markdown Manager. It allows you to show a higher price that has been crossed out, in addition to the actual price of an item.
In order to use Strikethrough when listing from SureDone:
1. Click Settings > Channels and expand your eBay Options section
2. Scroll down to the Strikethrough toggle and set it to On
3. Create a new product or start editing an existing product.
4. In the Editor, enter the Strikethrough dollar amount in the MSRP field in the General section. You can use this field when using the Bulk Upload functionality as well. See the guide here on Bulk Uploading.
