@Richard.Dane, if this goes against the forum rules my apologies, please remove the thread in that case.
For anyone looking for a nice discount on a Tidal subscription, there is currently a group-buy taking place on the hifi [dot] nl website which offers 24 months of a Tidal Master subscription for 200 euro (8,34 per month) instead of the regular price of 480 euro (19,99 per month). The deal applies both to new Tidal subscriptions as well as for extending a current subscription. No further rules or limitations apply.
