I'm glad you have the will to send me several seeds.
You are a very good man, there are few good people like you.
I would ask you when you have a little time to ask in your state post, how can you send me safely to me for Serbia without a problem?
Each country has its own rules regarding the sending of parcels and letters.
Ask, how can you easiest, cheaper and safest to send, the envelope for the country of Serbia ? 
Let me know what you learned on my email address ([email protected])
I wish you all good, a lot of joy
A lot of greetings from my family and me :)
