Ok, (continuing with the court theme), we should go back and read the transcript.
Per cobblove:
Original deal agreed on was $2675.
Seller wanted payment via FF and buyer agreed to pay $2750 (an extra $75) to cover paypal fees.
Four days later seller says he has other offers including $2750 FF and asks buyer if he can refund the $2750 regular payment and have buyer resend as $2750 FF.
Buyer agrees to pay an additional $100 ($2850) to cover paypal fees (a second time) and also cover overnight delivery which buyer says seller already agreed to pay the first time at $2750.
The seller doesn't dispute any of this, except to say the additional $100 (from $2750 to $2850) was a voluntary payment from the buyer, omitting the fact that it was the second time the buyer paid extra to cover paypal fees.
These are the facts as I understand them your honor from reading the posts above.
