PRODUCT QUESTIONS: 1) are there any plans to offer sliding scale pricing? E.g You can offer 3 different prices for the same product, and people can select which option is appropriate for them based on their financial situation. 2) Are there any plans for 'add-ons' to payments? E.g. someone is paying for a program, and they have the option to check a box and add an additional $50 to their payment to receive a 30 min 1:1 session with me during the program. Thanks!
