Product where the buyer can set the price?

Is there a way to have a product in webflow where the buyer can insert any dollar amount they would like? I would like to have a way where anyone on the site can leave a tip for any of the sellers on the site and add that tip to their cart. (example: the buyer finds a few products with set prices and adds them to their shopping cart and then wants to leave an additional tip amount they chose to one of the sellers)

If you don’t see the option in the University documentation then it is safe to say it does not exist for now. I have seen references to using third-party e-commerce solutions that may handle this type of requirement. They are listed in the University as well.
