I didn't think you'd make the complaint...you'd walk rather than draw attention to a cannabis seed deal that didn't go right. Not long ago you said you didn't want to jeopardize your family by posting pics online....making a claim on a MO for a bad seed deal is not something you'd do...or me either for that matter
So for me, cash is easier and has no records. I send priority mail.
In my opinion, tracking your inbound money is something that will work better for you in case something happens. I use priority, costs $7 approx and I get tracking. I know that it's a bit more expensive if you are not in the US..... You just need to prove your money got there and a blank MO doesn't do much in that regard. A blank MO would be a gift to a MO thief, not a deterrent.
