BLACK FINGER OF DEATH!! Seen it before on cold storage roses!
Cindi, the first thing I would do is send these photos to the supplier!!! I am not familiar with Hortico and what sort of quality they usually supply but I think the two on the left are definitely NOT up to standard. You might be lucky and after cutting all the black stems away, they might still be ok. BUT if I was you, I would ask for replacements!
Also, when you cut back those two, remember to disinfect your clippers so that you don't infect any of you other roses.
Just my opinion but I would be very disappointed especially when as you say the shipping was more that you expected and then you get roses which are not up to scratch!
