I am quite sure that the person who posted that auction and the person in the picture are NOT the same person.
I would bet that this auction was posted by the pictured woman's bitter ex-husband, or her boyfriend's ex-girlfriend of something along those lines.
Why do I think that? Well, here are some quotes from the auction:
"Seller's payment instructions & return policy:
Pay-Pal. My BEST pal; in fact, we're more than just pals; it gets me more excited than my husband ever did. I combine alcohol with tranquilizers so I will certainly combine shipping. Money orders are an insurmountable stress for me; I'm already an emotional wreck. Use it as a last resort. Put me in your FAVORITES list! I have the most appalling things on the site. E-Babes, I have so much JUNK and BAGGAGE that two sherpas follow me around. (One of them is kinda cute)"
"It looks like I'll break down and be driving van soon BEING THAT I'LL NEVER GET LAID AGAIN... So, I'll come to your house, in my freaking fat van, in OVERALLS"
I sense a little bitterness here .... yes?
And, honestly, no one is going to take this seriously. For one thing, the above quoted nonsense. Secondly, why would anyone, even an idiot, think paying someone $500 plus $.30 per mile to kill their pet "painlessly" is a good deal .... when a vet will do it for $50 to $100 ... and Animal Control will pick it up and do it for free.
Yes, it's in bad taste. But I don't think it is too dangerous.

"We are raised to honor all the wrong explorers and discoverers - thieves planting flags, murderers carrying crosses. Let us at last praise the colonizers of dreams."- P.S. Beagle
"All that is gold does not glitter, Not all those who wander are lost; The old that is strong does not wither, Deep roots are not reached by the frost. From the ashes a fire shall be woken, A light from the shadows shall spring; Renewed shall be blade that was broken, The crownless again shall be king." - J.R.R. Tolkien
