Hello everyone

So I've been looking to get a yorkie

for a long time now and I didn't realize how hard it is especially online where there's a lot of scam! So far I found a family that sells yorkies for a pretty reasonable price..
what do you think about this:
Purebred Yorkies - orange county pets for sale - backpage.com
They are about 20 days and I am going to see them tomorrow but I dont know how are they gonna look when they grow up. The mom looks like its purebred and they said that they'll bring the father.
Usually purebred yorkies range $1000 and up but I am not sure why they sell em for so cheap?!
Advice anyone?
