As I said in the OP, I might have the original receipt email but I'll have to dig around. I do have several subsequent receipt emails for other purchases on the account.
Like it says,
Selling 7 digit account (starts with 4) in good standing. Have owned account since new.
I might have the original purchase EM, but I'll have to go looking. I do have subsequent purchase EM's however.
If folks want screenies, they can PM.
I'm not desperate to sell, but...
