Is in-app store a compromise solution to stop users claiming for deposit refund?

ofo recently launched an in-app discount store enabling users to convert unclaimed deposit into virtual tokens with which they can place orders for certain daily consumables, including coffee, tissues, and even wine. However, virtual tokens are not usually of sufficient value to cover the full cost for a single product so additional payments from users have to be made. The store is currently only available for users who haven’t successfully reclaimed their deposits.
