Life / Flowers on a grave in Poland - how to order and deliver from abroad? [9]

So I was able to find my father's cemetery; he was buried in the cemetery of Bd Vincent Kadłubek parish in Jedrzejow.

How would I go about ordering flowers to put on the grave and how would that be handled money-wise? Does Poland use Paypal? I am at a loss as to how to do this. It looks like the cemetery mgmt company Jarosz handles flowers, just not sure how I would pay. They can't be ordered online so I'm concerned about the language barrier over the phone.

Any advice appreciated! Thanl you!!
