Buy Seeds - Seller recommendation

[Metallising]

Hi,

This is probably the most recurrent subject in this sub forum on this board.
So here it goes again: Can someone give me some advice on where to get seeds from a reputable seller?

I have found people selling seeds online but not trustworthy IMO.
I asked to my local orchid association but no luck, I sent messages to dozens of people I follow on Facebook related to orchids but no one have seeds for sale.

There's an Australian guy on Facebook selling seeds: Flask List

Has anyone tried to get seeds from him?

I have Bletillas seeds for trade if anyone is interested.

Thanks.
