I use Proton email alot won't except it If not sent through a secure email. I don't blame them you want to be secure with the transaction. Also make sure it's the correct email your sending it to. It's available on SST.
I just placed an order this week. I realize that AG is very busy with the sale. But with the savings I received and the quality gear they produce I willing to wait. Thanks for everything Aztecagold!
