lately I asked at fabfilter for a subscription/rent-to-own model...
This was the answer:
So, if there are more people like me, who want to see something like this from Fabfilter... then please demand, demand and again demand it...We considered this payment method, but decided not to offer it for the moment. We might reconsider in the future if there's more demand for it!...
Btw, very nice reply and fast as lightning... thx very much Fab-Team
