Refund, Return & Cancellation Policy

Store credit has no minimum spend, no expiry, and can be used in full on any single order at dropy.in. If the customer requests a refund to the original payment method instead of store credit, a 5% processing fee will be deducted from the refund amount to cover payment gateway and administrative charges.

For orders above ₹10,000 where a partial advance payment is collected:

  1. Order cancellation is allowed only within 24 hours of placing the order.
  2. After 24 hours, the advance amount will not be refunded, as procurement of the product is initiated immediately.
