Watch out for the short, grey haired haggard woman from the Green Hills Flea
Market in Nedrow, NY.

Bought a box of misc. video game equipment for $40 as this flea market was
closing (including 2 SegaCD-2 systems and two Sega Genesis 2 systems..
missing many hookups) only to bring them home and discover they reek
overwhelmingly of cat urine.  (Very hard to detect in the flea market
environment due to other strong odors in that building)  Had to lay down
plastic bags on the floor to untangle and examine each item.  We couldn't
touch anything else after handling any of the items else the urine stench
would transfer instantly.  Upon closer examination, we found the piss was
caked on many of the items and it was so strong our eyes were watering.
Regardless, we considered purchasing specialized cat urine remover for the
items to see if anything could be salvaged.  So we tested out the equipment
to discover only one Sega Genesis (barely) worked.  Both SegaCD systems were
borked, a SNES controller freaked out and would change what each button does
during gameplay, RF adapters turned out to have stripped wires, a SNES AC
Adapter would shut our SNES off at random intervals and other various items
brought more tears to our eyes.  The systems had amazingly all been pissed
on directly.  You could see the caked on urine inside the systems.  They
were even rusted inside.  Ewwww.

Anyways, after a short debate (nothing we could do with them; couldn't even
keep them in our homes) we bagged up the goods and decided to head back to
the flea market the next week in hopes of reaching some sort of deal to
reclaim at least some of our losses.  We've encountered many great dealers
who offer money back on broken goods so we crossed our fingers.  After we
politely informed her of the condition of the goods she sold us, she
immediately threw a fit and implied we were a couple of lying scumbags.  She
proclaimed (repeatedly) there were "never any cats in here" and that the
goods did not reek when she sold them to us.  Upon offering to open the bag
and let her have a whiff, she promptly (and in her now patented "You are
thieves" manner) refused.  She then went off on a spiel about how great the
deal was she gave us;  how she normally sells "Sega systems" (are they
broken also?) for $40 alone (lol) and how we should be thankful she gave us
the deal she did.   After repeating herself a few more times, she called
over another dealer to support her claim that there have "never been any
cats in the building" (nevermind the fact the items were likely pissed on
before she bought (or stole, or found or whatever) them.  This same dealer
she called over then tried to work something out for us.  He was cool and
tried to get the woman to budge but she was willing to fight to the death.
Her attitude was unbelievable.  She tried her hardest to make us out as two
evil young people who were out to get her.  We expected the possibility of
no refunds but God damn.  In the end, she turned her back to us and told us
we could choose a couple of "Sega Games" (NES carts) she had on a shelf.  We
ended up with 3 filthy NES games.  We (of course) left the stinky goods with
her.  I told her she may want to inform the next person that's interested in
those items of their defunct and cat stinkified condition and she replied
with a classy "NO, I'LL JUST THROW THEM OUT".  This was our first really
shitty flea market. :)

So anyways, buyer beware ruled supreme in this case.

A few more funny moments from this experience:

We paid for the goods with two brand new multi-colored $20 bills.  She
examined them for a while and then asked us how she could tell they were the
new ones.  Har.  Color blind as well as evil?

Deep inside the box was a weird looking joystick that had a CAT COLLAR tied
around the wires, lol.

My girlfriend's male cat went apeshit over the equipment and the bags they
were in.  Wouldn't leave them alone.

BEWARRRRRRRRRRRRRE.
