Reward Vonka for her performance and make her a very happy girl. All money goes to the model.
Please note: Because of the store-wide discount, if you want the model to receive $40 or thereabouts, you would need to enter $60. This will attract a 25% discount and the amount actually donated will be $45. Should you want to donate $100, the store discount is then 30% and you would need to enter $140 to get an actual donation of $98. If you're not worried about the discount and happy that donating $40 turns out to be $32, then that's also fine. This means that your card will be only be charged $32.
