So this is XING’s attempt of a “promotion”? They advertise this as 2 months for the price of one:
Honestly though:
Happy Hour membership: One month’s membership for 5.95 € + one month for free (offer valid once only), then three months’ membership for 17.85 € (working out at 5.95 € per month)
…in my book this works out to be 5 for the price of 4… a savings of 20%, versus 50% as advertised.
