You could also try listing things on craigslist.

They have one for Seattle. No fees. All local. Sometimes, you can sell
something the same day you list it, for the price you want. You can
always list stuff there and then put it on ebay if it doesn't sell
locally.

Also, since you are in the Seattle area, check out this vet.

They do not require appointment. They are great to work with. I grew
up in West Seattle, so we always went there. We moved out of state and
returned to Seatac, and we still go there for most of our vet care.

Because they are in a lower income area, they do charge lower rates
and are listed on the  low cost spay/neuter national website. It's
been awhile since I have needed that service, but their rates were
less than half of the places in Seatac and Des Moines.

You could probably save some money by going there, and I guarantee you
will get good treatment. And they won't try to pad the bill. When they
diagnosed Jenny with an enlarged heart, I asked about further tests,
and they said to wait a year and do another x-ray. Unless that showed
a noticeable change, or she started having trouble, then the expensive
tests would be useless. And they were right. Her heart was not
unhealthy, just larger than ideal for her body size. And a simple diet
was the solution. They didn't even sell me diet food. They told me to
put green beans in her kibble to keep her satisfied (low calories, no
fat). And we've been doing that for 7 years now. No problems.

My only wish is that they were closer. Otherwise, they are the best.
