Subscription purchase options beside a one-time order
Proud Mary Coffee puts one-time and subscription cards next to each other, with the one-time choice selected in the captured state. ILIA pairs the purchase modes with a delivery-frequency dropdown and a separate explanation dialog. The choice should say what repeats, how often it arrives and what each shipment costs before the customer adds it.
Discounts need context too. Dieux changes the price according to the replenishment interval, while Bloom adds a per-serving figure. Keep the charge for the whole shipment visible and distinguish any first-order incentive from ongoing cost. An explanation dialog can hold more detail, but it should not be the only place that reveals the recurring commitment.
Cart subscription offers and changes to the plan
Stumptown places an upgrade offer beneath a one-time cart item, while La Colombe presents an offer after the initial add action with a route to keep the original purchase. An offer at this stage should identify the item it changes and leave the customer able to continue with their earlier choice.
Follow the selection through each purchase area. Momentous exposes subscription controls in several places; the product, quantity, interval and price should agree across them. Beam’s gift also needs to follow the plan’s eligibility when someone changes their mind. Several captures stop before billing or a reversal, so test those transitions rather than assuming the displayed configuration proves the complete order works.
