title: Stripe Subscription Plans of Varying Amounts
body: <p>I am working on a donation form for a charity and they have requested a monthly donation plan where the user can choose whatever amount they would like to give. </p>
  
  <p>I know I can make individual plans (i.e. if they said monthly donations of $5, $10, or $20 dollars) I could make three different plans and subscribe users to them. Is there a way to avoid making new plans for every varying subscription amount? </p>
