I don't negotiate against myself.

Feel free to make an offer. If, by your offer, you appear to be serious, I may make a counteroffer.

Notwithstanding the above, I had a bad experience selling to you in the past. I am not inclined to make a deal with you without pre-payment in full. For anyone else, I'd be happy to use escrow and/or send the T1 and the PSU prior to payment.
