Volvo / Polestar cooperation with plugsurfing

I’m expected to get my Volvo XC40 P8 next month and I’m trying to orient myself in the jungle of the various charging providers (unfortunately, I’m completely dependent on the public infrastructure). For me, all of this is still extremely opaque at the moment … Volvo / Polestar has been cooperating with plugsurfing since last year. What I haven’t been able to get from the flowery press releases so far: What’s the advantage of the Volvo / Polestar driver from this Koopera? Is there, for example, an attractive “house rate”? The “generally accessible” tariffs of plugsurfing seem to me to be rather less attractive, especially after Plugsurfing Plus was reinstated in Germany … Gruß, Andreas
