With Barzahlen consumers can buy online and make payments with cash at thousands of stores nationwide.
Here’s how Barzahlen works. With participating online shops, consumers can use the Barzahlen option to pay for purchases owed. You simply place your order with Barzahlen and print out the given receipt. You then take that receipt into a Barzahlen Partner shop and they scan it and you pay in cash. Once you pay, your order with the retailer or merchant will be fulfilled.
