You may use a similar method to sell several products and services that are to be purchased in single units. For example, you sell tickets to yoga classes, and each class is priced differently depending on the time of day.
If this is the case, add a block from the "Plans" category (for example, the PL100 block) and assign links to each button, e.g., assign #order:Morning Class =100 to the first button, and #order:Evening Class =120 to the second button.
Once a customer clicks on either button, they will be redirected to a payment system page where they'll be able to pay the respective price.
