Have you changed your mind and closed the shop's window being bored and frustrated with this process?
We in Getsocio have faced such situations and at some point decided to design a solution to eliminate these inconveniences for customers.
Each daily deal site on Getsocio can now handle multiple currencies.
The amount is automatically converted from one currency to another when needed. The exchange rates are fetched every day from European central bank.
There are two practical use cases for multiple currencies
Sometimes an order needs to be refunded. It happens quite rarely, as the most of the daily-deal site customers are happy with their coupons and enjoy the discounted service offered. But from time to time customers claim they cannot use the coupon for some reason and ask for refund.
Of course, it is always possible to issue a refund via payment system. But what happens to the coupon?
Recently we have made it possible for site owners to refund an order in Getsocio admin section. When an order is refunded, it will destroy the coupons, void the payment transaction and also will adjust the Getsocio fee, so you don't have to pay the commission for refunded orders.
Of course, it is up to the site owner to decide should they refund each particular order. Having a payment/refund policy posted on your site is a good idea too.
