Why is there a time limit for completing a transaction?

Our sales are limited, in both time and stock. But we want to give all Zalando Lounge members the chance to snap up our incredible bargains. That's why we empty your shopping bag after 20 minutes. Once the time's up, the articles are again available to shop for all our members. If you put another item in your shopping bag, you'll get an extra 20 minutes to complete your purchase.
