Even Selling Football Cards is becoming a TASK!!

You would think card selling or heck any selling would be easy to do. People pay and you send them their stuff. Nic and easy. But it is situations like this one why I want to get out of trading/selling cards on all forums and groups and just buy the cards I want off ebay and comc:

Buyer:
I want them ok 15 works ill buy them both what is ur adress
13:50
David Aguero

13:51
Buyer:
I wanted to send cash through mail?
So I'm going to send 15 with dc in bubble mailer I can get it mailed out by 315
13:52
David Aguero
Ok and it was for the peppers and Moss. Once I get payment I will mail out
Buyer:
Can u ship when I give u dc#
David Aguero
no
I ship when I get the money

Which he tried to get me to send again several times before payment:
Buyer

19:40
David Aguero

19:40
Buyer

19:40
David Aguero

19:40
Buyer

i dont get what the big deal is
19:40
David Aguero
and I haven't gotten them
because I don't know you and you could have sent an empty mailer for all I know

Well I get the money and after an hr of trying to make sure their address is right since I couldn't read it on the padded envelope.:

 I ship. And I give the buyer their DC:

Well today I get this message:

Buyer

David Aguero

Well  its just getting to be too much honestly. So I am seriously thinking it is best to send inall my cards that have some sort of Value to COMC. Might relief some of the stress.
