UserWay button modifications, cost of modifications

Hello! Your welcome email stated that:

“For only $10 you can modify the widget footer, remove the donate link and enable other customizations.”

Does this $10 include adding my logo to the bottom of the button and having keyboard navigation and big cursor in the button’s menu? Does this $10 include everything to make my button look like the one in the link of the custom branded widget? Also, is this a one-time charge of $10?

In addition, I looked at the Remove the Donate link. I don’t understand this statement: “Removing the “Donate Link” is part of the widget’s white label features.” What is a white label, and what do I change it to?
