The question is in the OP - Does Steinberg ship from outside the UK? That’s the only reason I can think why this is taking so long…
5 days ago it was ordered, it has still not arrived even though it cost £15 for delivery. I imagine such delivery cost would be an express delivery yet it is not.
I could have ordered one on Amazon Prime and had it delivered next day for £10 less, which in future is where I will order.
