You can change the Upsell message to show the product's title, product's price and product's original price. Here is how to do it:
Go to your LimeSpot Admin Panel > Conversion > Website Personalization > Designer
Go to the Cart Page
Click on the Upsell recommendation box
Click on Basic and find Title
Change the Title to the following:
Add title = {title}
Add price = {price}
Add original price = {original-price}
Add vendor = {vendor}
Example: Title = "Would you like to add {title} for {price}{original-price}?"
On your live store it will show: "Would you like to add item for $17,00 ($20.00)?"
