As someone who just did a necropsy and Viral testing for a newly purchased animal that died with no symptoms just as it was suppose to finish quarantine. I would avoid just buying up whatever 'great deals' you find unless you can properly keep them isolated.
I stupidly had this new pickup in a baby rack in another room because I had trusted the breeder and worked with them in the past. Thankfully everything tested negative. We don't know what happened... but it was a big kick in the ass and reminder to never do something so stupid again regardless of where I got them. I could have wiped out my holdbacks from last year.
